Pulse Compression Mtd Radar Simulation And Interference

In this dissertation, it is studied that the simulation and modelling of the pulse compress MTD radar. And some jamming signals to this kind of radar are discussed on the basis of the simulation model.First, the return signal model is set up. The target return signal, clutter which has gauss power spectrum and noise of the receiver are included. In the subsystem of the receiver, to get I Q two-channel digital signal, return signal was perpendicular sampled at Intermediate frequency. In the subsystem of signal processing, digital sidelobe cancell block, digital pulse compress block, adaptive clutter canceller block, doppler filter and constant false alarm rate block are respectively discussed and set up. In signal processing, data in the same coherent processing interval form a matrix, and the data processing was completed based on the matrix. Data are processed with the row vector or column vector respectively when needed.The whole simulation and modelling was completed with the software Cadence SPW. Some functional blocks are set up with the basic block provided by SPW, and some is programmed with C language.After the simulation of pulse compress MTD radar, the effect of some jamming signals is analyzed. Especially, the jamming signal of high pulse repeat frequency is discussed.
