Wideband radar with high resolution plays a more and more important role in modern war. mainly used in fire control radar, surveillance, guidance, guidance radar system. With the wide application of radar, the detection demand grow with each passing day. This thesis is focused on wideband radar detection method based on DSP.Firstly, establish the radar echo model, including the general radar echo model and clutter model, model of broadband radar echo and clutter model, the model of clutter background (Rayleigh distribution, accumulation and distribution, Weibull distribution,K distribution), and carries on the simulation of echo and clutter model. Secondly, the broadband radar traditional detection algorithm, and the radial detection algorithm, generalized likelihood ratio detection algorithm and M/N detection algorithm for the performance simulation analysis. Third, the new method of wideband radar target detection, is mainly to the statistical characteristics of difference detection algorithm based on the research and simulation and analysis based on information entropy detection algorithm. Fourth, based on the hardware and software of two new detection algorithm and Realization of DSP technology
