DETECTION OF MULTIPLE TARGETS BY A MULTISTATIC RADAR

Abstract

Multistatic radar systems with several transmitters and receivers introduce not only new qualities in area surveillance as well as in hardware minimization but also new problems in signal processing and target detection and tracking. This paper deals with multistatic radar system consisting of several independent bistatic radars processing signals scattered of surrounding objects. The measured data, e.g. time delays and Doppler frequencies at individual radar are therefore not associated with a particular target. An optimal detection method should find the proper associations among a great number of their possible combinations. In this paper a detection method, based on a probability hypothesis density function (PHDF) is described and tested using a mathematical simulation in Matlab.
