The high peak sidelobe is its main problem instead of its superiority on the simplicity and Doppler tolerance characteristics. The curve-shaped Nonlinear Frequency Modulation (NLFM) has been developed for overcoming this lack and prior investigation showed that this method provide lower sidelobe suppression than LFM. For obtaining the overall performance to be compared with LFM method, this research will investigate the curve-shaped NLFM in the case of Doppler effects and high level background noise. The Doppler effects considered in this research consist of two including center frequency shift and time dilation. Then, the background noise investigated is Gaussian distributed noise with signal to noise ratio (SNR) levels in range 0dB to −20dB. According to the simulation results, in the Doppler shift case, the curve-shaped NLFM is more sensitive than LFM as other NLFM drawbacks. However, this method is better than LFM in the time dilation scenario. Then, this pulse compression also has better detectability than LFM in the certain case of high level background noise condition.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125427618","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}

The reconfigurable mechanism of the antenna can be achieved by the implementation of radio frequency (RF) p-i-n junction (PIN) diodes across a T-slot developed on the feed line of the antenna. The antenna is designed using textile based material for wearable applications. The use of a full ground plane and T-slotted feed line with RF switches implementation enabled radiation to be directed away from the human body, thus minimizing absorption and ensuring user's safety. Most importantly, the antenna is frequency-reconfigurable for operation in three bands; 1.8 GHz, 2.3 GHz and 2.4 GHz, and is potentially useful for location tracking of human.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125978162","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}

Microstrip antenna array with a multi-layer structure is a potential candidate. The antenna should work in a wide spectrum interval and should be multiband. The proposed antenna system consists of three layers. In the middle layer, there are two rectangular microstrip patches, which are fed by an electromagnetic coupling through some slots from the bottom layer. On the top of the patches, a gridded structure with 6×3 rectangular microstrip patches is built to enhance the gain. This paper calculates the antenna system with a commercial software package. The calculation results show the antenna system operates in three frequency bands in the spectrum range of 40 GHz - 80 GHz. The gain obtained in the simulation is about 8.65 dBi.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131962822","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}

One of external interference is another radar placed in the nearby location which behaves as a jammer affecting the radar maximum detection by decreasing the signal to noise ratio (SNR) level. This paper describes the effect of external radar as a source of jammer in the main-radar performance. This can be occurred when multiple radars are used in one platform. The radar model was simulated by radar parameter which was already being developed in the lab. There are three scenarios presented. First condition is the absence of interference, second one is where radar and jammer are installed in one place, and the last is when radar is influenced by jammer from another place. The presence of jammer degraded the radar performance by decreasing the radar maximum detection as in scenario two. The existence of another radar in one platform should be considered by the radar designer to optimize the radar performance.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130211626","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}

In this research, AD9956 DDS is used to generate short and long pulse signals that will be used to modulate the determined carrier frequency. The short pulse is formed from DDS single tone waveform mode, while the long pulse is formed from DDS linear sweep waveform mode. Both of pulse signals are digitally triggered by microcontroller to set their pulse width and frequency of repetitions.

These sensors sense the environmental data, according to the application, and then communicate with each other, and finally send these data or readings back to the base station. WSN security is an important issue, since motes are usually left to operate unattended in the environment where they were deployed. Intruder may inject false data into the network, thus strong security mechanisms are needed to be implemented in order to protect the network against malicious intruder or attacks. This paper proposed a key distribution and authentication protocol designed to achieve some security requirements of WSNs. The paper introduces a simple protocol for shared key discovery and authentication of massage and entity. The work assumes mobile nodes and proposed a re-authentication protocol for nodes to re-authenticate themselves in the new location. The efficiency of the proposed protocol has been ensured in terms of energy consumption, packet size and the security requirements achieved.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114341893","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}
