Pd Spw Simulation Of The Radar Receiver And Signal Processing Systems

This Paper describe realization of receiver and Signal Processing machine of some Pulse Doppler Radar detailedly, giving principles for main modules, establishing the mathematics model, combining simulation. That air Pulse Doppler Radar work with range gate in HPRF and MPRF ,and work includes the LFM(line frequency modulation) and barker code + MTD(Moved Target Detection) at LPRF. We use the effective EDA simultiaon tool Cadence SPW4 to realize the system with the mold method. The system has very flexibility. The signal environment module and data processing module were completed by another two classmates. Then, we used the constructed system as plat to complete interference and anti- interference experiment.This article is arranged as follows : the first section is preface, introducing the origin ,great significance, domestic and international research development with myself job; the second section summarize PD (Pulse Doppler) radar and PC (pulse compression) radar firstly, giving the system frame diagram realized and the flow chart of receiver and signal processing machine; the principle and realization of main modules in receivers sub- system such as AGC(Automotive Gain Control), distance gate rearranging, clutters processing and quadrature coherent detection are described further At the third section; the principle and realization of main modules in signal processing sub- system such as pulse compressing, clutters processing,, doppler filter group, automotive detection, CFAR(constant false alert ratio) with fixing mind algorithm are described further at the fourth section; At the fifth section, A part about part simulated data and result, we giving out the out put of receiver and signal processing machine sub-system at suffering interference , no suffering interference and systems adopting anti- interference measure ; Chapter 6 is end language, I summarize the full paper and give some outlook.
