The CDMA signature is created from a sequence of modulated linear chirp functions. Reception begins by separating the radar and signature bands via a bandpass filter, digitizing, and feeding the resulting signals into separate data buffers. The receiver is time sychronized and the Doppler shift is estimated by matched filtering the radar waveform. The CDMA signature is decoded by convolving the chips with a Doppler adjusted matched filter, thresholding, sampling at the peaks, and finding the closest signature in a codebook. This paper illustrates these waveforms, their receiver, and their performance against Swerling III and IV targets, noise, and a Doppler shift.","PeriodicalId":193529,"journal":{"name":"2019 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116902421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several applications in the health domain utilize the WSNs to diagnose the disease and cure the patients. However, there is threat and risk involved for exploiting the privacy of the patient and deteriorating the performance of operating tools and systems. There are few existing approaches handling the attacks to maintain the privacy issue of wireless body area sensor networks (WBASNs). Most of the threats are expected on the Medium Access Control (MAC) sub-layer that affect the performance of WBANs. In this paper, we introduce privacy preserving Medium Access Control (PP-MAC) to detect the selfish attack. The algorithm aims to save energy because selfish attack leads to additional energy consumption. In this type of attack, the illegitimate node has edge over the legitimate nodes at the MAC sub-layer. As a result, the illegitimate node consumes the resources negatively. The effectiveness of our proposed algorithm is tested by using OMNET++ and compared with other known existing MAC protocols designed for WBANs. Based on the simulation results, our proposed protocol performs better than other protocols in detecting the rate of selfish attacks, saving the energy, and performance throughput.","PeriodicalId":193529,"journal":{"name":"2019 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114462817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This creates a need for Advanced Driver Assist Systems (ADAS) which can ensure safe travel. To tackle the above challenge in existing the ADAS, Intra-vehicular communications (V2V) and vehicle to infrastructure communications (V2I) has been one of the predominant research topics nowadays due to the rapid growth of automobile industries and ideology of producing autonomous cars in the near future. The key feature of V2V communication is vehicle to vehicle collision detection by transmitting information like vehicle speed and position of a vehicle to other vehicles in the same location using wireless sensor networks (WSN). On the other hand, Unmanned Aerial Vehicle (UAV) systems are growing at a rapid rate in various aspects of life including dispatch of medicines and undergo video surveillance during an emergency due to less air traffic. This paper demonstrates the practice of integrating V2V communication with Thread, one of the low power WSN for data transmission, to initiate adaptive cruise control in a vehicle during a crisis. Also, UAV systems are employed as a part of V2I system to provide aerial view video surveillance if any accident occurs.","PeriodicalId":193529,"journal":{"name":"2019 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115141287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While electrical power provides many performance and efficiency advantages, the added capacity also increases the available electrical fault current. Consequently, it is critical to understand the response of the electric machine to a fault and design protection schemes to de-energize the machine in order to mitigate any potential damage to the aircraft.This paper experimentally compares the response time of a wound-field synchronous generator when simultaneously shorting the terminal windings and opening the exciter field windings for no-load and loaded conditions. These results are compared against the response times to fault conditions in which the generator continues excitation throughout the shorting event. This experimental set can be used to empirically evaluate the magnitudes of peak current and the stored energy of the wound-field brushless electrical generating system. A subset of the experimental matrix is used to simulate a crowbar across the generator armature windings.","PeriodicalId":193529,"journal":{"name":"2019 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127769005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate and real-time perception is very important as it constitutes the basis of important tasks such as decision making and control. The latency of the sensing pipeline is a major limiting factor for the agility of a robot. A novel sensor called an event camera has been recently developed to overcome the limitations of traditional frame-based ones. Event cameras mimic the human perception system as they measure the per-pixel intensity change rather than the actual intensity level. This paper presents our initial investigation of this novel sensing modality by building an event-based dynamic multi-cluster tracker. This can constitute a building-block for higher-level event-based multi-object trackers. The clustering algorithm will be experimentally evaluated in different scenarios including its use for mapping.","PeriodicalId":193529,"journal":{"name":"2019 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"150 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124606011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To prevent this, more gradually increasing or steady ascent/descent/turn rates should be commanded. In longitudinal, a guidance law is developed using aircraft dynamics that both keeps trim conditions salient while also tightly constraining ascent/descent rates, which can then be optimized through the linear quadratic regulator technique. Furthermore, this base guidance is decoupled from initial conditions. In lateral, a curvature path planning navigation is introduced to eliminate step input controls in turns. Results show that the aircraft can track the path as well as traditional algorithms, while also producing more reasonable reactions to lateral and longitudinal errors.","PeriodicalId":193529,"journal":{"name":"2019 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126416858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
