The Analysis And Simulation Of Radar Oppressive Jamming

This task consults some basic radar theories which are currently recognized, and uses the modular design which divides the whole system into subsystem of signals, subsystem of receiver and subsystem of signal-processing. The subsystem of signals simulates echo signal, receiver-noise, clutter and oppressive jam, which can be selected flexibility. The subsystem of receiver simulates limiter, A/D and orthogonal dual-channel phase demodulation. The subsystem of signal-processing simulates pulse compression, MTI, MTD, envelope demodulation, CFAR and threshold decision.This task uses VC++6.0 to realize the interface of simulation software and all of the algorithms, and writes result into files, then uses Matlab7.0 to read files and complete the drawing for analysis. All above modules analysis the specific algorithm completely and interference that oppressive jamming impact signal detection in radar under different SIR by Monte Carlo simulation, and give a lot of formulas, flow charts, the charts of simulation result.
