In recent past, MIMO radar has received lot of attention from researchers. MIMO radar can be deployed in many configurations based on the end goal to be achieved. Broadly, there are two different configurations of MIMO radar viz., statistical MIMO and coherent MIMO. In coherent MIMO, the radar can be again a omni MIMO or subapertured MIMO. There are different processing schemes and waveforms which could be used for coherent MIMO to achieve different performances. Irrespective of the configuration used, the resource manager for any agile radar plays a vital role in maximizing the usage of radar resources. This paper deals with resource manager for MIMO radar and brings out the savings of radar resources in MIMO radar vis-a-vis phased array radar.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126913720","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 jamming of Commensal Radar (CR) systems, and possible ECCM responses to such jamming have not received more than a passing reference in the open literature. We examine a specific case of an FM Band Commensal radar with a multi-receiver configuration (single transmit site, many spatially distributed receivers) and find that although modest jammer power can be very effective in jamming the CR, the unknown geometry and frequencies of operation of the Commensal Radar (CR) will make it difficult to jam in practice. Simple null steering by the CR receivers is very effective. We also note that the CR system requires excellent Electronic Support Measures (ESM) to be aware of electronic attack. The paper reviews the tactical situation, and the very sparse literature. This is followed by some analysis of the effect of noise jamming, followed by simulations of jamming, with and without receiver null steering, as well as some self-protection jamming.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128898384","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 paper investigates the performance of Constant False Alarm Rate (CFAR) algorithms on maintaining a fixed false alarm rate when windowing is used to reduce the sidelobes in both the slant-range and the Doppler domain. A Monte Carlo simulation was used to investigate the performance of Cell Averaging CFAR (CA-CFAR) and Ordered Statistic CFAR (OS-CFAR) algorithms. Results show that the windowing operation induces correlation between the samples. This correlation causes a large error in the Probability of False Alarm (PFA) when the CFAR scale factor was calculated using closed form equations, which assume that the samples are uncorrelated. In order to maintain a fixed false alarm rate when the windowing operation is used, the scale factor value should be calculated by simulation.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122004628","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 system design is composed of three passive radar sensors providing the location of potential targets by the measurement of time-difference-of-arrival (TDOA) of direct and reflected echo signals and calculation of the TDOA ellipsoid intersections. This paper primarily investigates a method of suppressing unwanted signal returns from wind turbines blades in passive radar systems. A signal processing procedure is proposed, which suppresses the returns of rotor echoes, while allowing the detection of target returns. The validity of this approach is demonstrated with data obtained from a PARASOL passive radar system.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126596733","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}

It provides picosecond accuracy timing based on a 1 Gigabit Ethernet (1GE) fibre data network, where all routers are specialised White Rabbit hardware. WR is built over the IEEE Precision Time Protocol (PTP IEEE 1588-2008). The operation of networks of radar sensors requires precision time distribution for collaborative target location, as well as excellent, low phase noise to enable precision Doppler measurements. This paper investigates the potential of the WR for network radar, and compares it to other possible solutions. The radar requirements are defined, followed by WR architectures that could meet these needs. The need of WR for a fibre link is clearly an issue for some applications.

In this paper, we demonstrate the capabilities of OptiSDR in a Radar DSP case study, and show how OptiSDR achieves up to 50 times (50X) speed-up as compared to the hand-crafted Matlab and Octave scripts for the NetRAD pulse compression algorithm. We also show that, while hand-crafted CUDA-Qt implementation of the same pulse compression algorithm presents up to 2X speed-up against Op-tiSDR, this was minimized using platform-specific optimizations by efficiently utilizing available computing resources such as number of GPUs, memory, and number of cores of a MCPU.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115504326","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 SNR diversity means that the SNRs in spatial diversity channels are different, which may degrade the detection performance. Further, the prior knowledge of the SNR is usually unavailable. Considering both aspects, we propose a cumulative contribution rate generalized likelihood ratio test (CCR-GLRT) detector. In each spatial diversity channel, the GLRT rule is exploited in order to obtain the local test statistic. In the fusion center, make the CCR of the local test statistics just greater than a given threshold factor. The global test statistic can be obtained by summarizing these local test statistics which satisfy the given factor. Simulation results show that our proposed CCR-GLRT detection algorithm outperforms the conventional centralized GLRT detection algorithm with the SNR diversity.","PeriodicalId":267194,"journal":{"name":"2015 IEEE Radar Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125828239","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}
