Study On The Methods Of Radar Function Inference And Software Design

Radar reconnaissance is an important branch of electronic countermeasures,it could detect useful information from enemy radar signal,guide their own take response timely and accurately.Radar function inference could give the working mode and threat level to their own through analyzing the parameters of enemy radar.Because of existing radar signal reconnaissance technology lack of inference method of radar function.This paper focuses on the function of radar inference modeling and simulation.In this thesis,the multi-function phased array radar is modeled,the transmitter model,the model and the working mode model are built,and the multi-function phased array radar signal captured by the reconnaissance plane is simulated.Secondly,we study a clustering analysis based on radar signal parameters and radar signal amplitude distribution histogram analysis.The method using radar signal parameters clustering analyzing radar signal received by the investigation,they should be divided into basic waveform corresponding to different patterns,and amplitude distribution histogram is used to analyze all kinds of basic waveform scheduling mode,so as to deduce the function of the radar.Through simulation experiment,the radar function inference method proposed in this paper can determine the operation mode of the radar in each period,illustrated the effectiveness of this method.Finally,the relevant software based on VS2010 and Qt is designed and implemented,including radar object simulation,radar object analysis,validation evaluation system.
