Single-station passive location based on equivalent SNR
Yang Zuojun, Shu Zhang · 2011
It is an essential requirement to realize single-station passive location of emitter target in the modern electronic warfare and information warfare. Single-station passive location system has vast application prospect, because of its properties of flexible, convenient, high concealing, far detection range and other advantages. This paper introduces a kind of single-station passive location method based on DOA (Direction of Arrival), PDRC (Phase Difference Rate-of-Change), and DFRC (Doppler Frequency Rate-of-Change). Equivalent SNR (Signal to Noise Ratio) as a measure to measure location accuracy is raised. Computer simulation of single measurement and conclusion are also given in the paper.
