Design and implementation on sorting and tracking processor for radar signal based on DSP

Radar signal sorting is an important part of radar electronic countermeasure. The measurement, analysis, target recognition and signal tracking of the signal parameters can be performed only after sorting the radar pulse signals from the random overlapping signal strings. This paper's research is based on the application of radar signal sorting in passive radar seeker. It focuses on sequence search algorithm based on the parameters of pulse repetition interval (PRI). And it designs and implements the tracking processor of passive radar information processing system based on DSP, which can ensure the real-time performance of the sorting signals and have practical values and referential values by experimental proof.
