Target detection performance analysis of single illumination and triple observation passive radar
摘要
Abstract
This work discusses the main problem and system loss in the aerial target detection system of omnidirectional passive radar.For the operation modes of radar system in SISO (single illumination and single observation) and in SITO (single illumination and triple observations),the detection ranges and measurement accuracies are analyzed under the condition that the numbers of array elements are the same.The target velocity expression is derived in SITO,and the accuracy of target velocity measurement is also discussed.The results show that SISO and SITO have about the same covering areas under certain conditions.Fortunately,SITO has the characteristics of high plane positioning accuracy,target velocity solvability,and low level of difficulty in technical implementation.关键词
