| The bistatic passive radar based on opportunity transmitters is a new system radar. Either using outer electromagnetic wave to detecting object than radiating electromagnetic wave, this radar is not easy to be detected by electronic scout system, and it has abilities of Anti hedgehop-assault,ECCM(Electronic Counter-Countermeasure), AARM(Anti Anti-Radiation Missile) and Anti-stealthy targets. It differs from other radars, because of its new system.Missions is completed on the base of passive radar signal processing:Firstly,The structure of bistatic radar, with radar signal processing further explained and the formula of radar-ranging introduced;Secondly,After the system requirements evaluated, the platform is selected and introduced;Finally,Pulse compression,coherent-accumulation, CFAR(constant flase alarm rate),dots-cohesion are implemented on the platform. A new method of dots-cohesion is introduced.Besides,the performence of every module is tested. |
