Pseudo Code Phase Modulation Interrupted Continuous Wave Radar Digital Receiver System Simulation

Quasi-continuous wave radar has a bright future for application in the high-teeh war.It is at a premium in many countries based on its advantages and has become a hot spot inthe technical field of radar. The pseudo-random-code phase-coded quasi-continuous waveradar is in research interiorly. The technology of digital simulation is controllable,reproducible, unbroken, safe and economical. Taking the research about the simulation ofthe receiving system of this kind radar with the simulation software is of great significance.This thesis discussed the wave forms of the pseudo-random-code phase-codedquasi-continuous wave radar. Then studied the working process of its receiving system andanalyzed its noise and clutter environment. This thesis constructed the simulation flowchart.This model included modules of producing of the echo, digital quadraturedemodulation, impulse compression, clutter-canceling and CFAR processing. The thesisselected the noise and the clutter model, introduced the simulation method. The thesis alsosimulated the signal forms of all processing nodes and analyzed them.The workrepresented the working dynamic current of the receiving system. At last this paperintroduced the multi-interval cycle MTI and applied it to the pseudo-random-codephase-coded quasi-continuous wave radar.This work achieved valuable simulation result.
