The Lfm Pulse Radar Echo Simulation And Processing

Modern radar system becomes increasingly complex, it's difficult to process with simple and intuitive method, therefore, the method of radar system simulation gets increasingly popularized. The method of radar system simulation has many advantages, such as economic, flexible, convenient and so on. It has been widely used in the field of radar research and engineering technology.This paper based on LFM pulse radar, does research on radar echo simulation and processing. This paper is divided into three main parts:radar echo simulation, radar signal processing and radar data processing. First, describes the methods of radar signal simulation and LFM pulse signal, then discusses the simulation of the radar echo signal, including the simulation of target echo signal, clutter signal and noise signal. Simultaneously, it gives the results of simulation. Then, it does research on radar signal processing, including measuring angle, beam forming, pulse compression, MTI, MTD, CFAR and target cohesion, completes detection of target by radar signal processing, and extracts the target's distance, azimuth, elevation and other information. Finally, this paper mainly analyzes the methods of radar data processing, including track initiation, point-track association, track supplement, track die out, deletion of remnant points and track display. Simultaneously, it gives the results of simulation. This paper completely gives the simulation and processing of LFM pulse radar system, the simulated radar echo signal, after the radar signal processing and radar data processing, eventually forms reliable tracks and displays them.
