Abstract


Technique of measurement in tracking radar is a very important and crucial field in radar technique. Tracking radar is widely used in weapon control, space exploration, shooting range measurement and many fields in military and national economy.In this thesis, we mainly studied the designment of waveform in tracking radar which is based on PSK, designment and concrete implementation of a ship-based radar signal processor, and simulated these algorithms according to concrete project. Taking the PSK signal for example,we discuss the theory of basic radar signal processing such as Monopulse tracking,Pulse Compress,Moving Target Detect(MTD), and Constant False Alarm Rate(CFAR) and target unite. Then, we show the methods in common use. Finally, we simulate these methods in MATLAB and show the figures of each stage. What is more,we have a view of the advantage and disadvantage between different methods through these figures. We also according to requirements of the project to develop a complete set of signal processing, and we also introduce a kind of method about solving the velocity fuzzy and using curve fitting to estimate Target position. For system design theory, This paper complete the simulation and verification.Through the simulation results show that the procedure of signal processing satisfies the design specification and proof of the system design is correct.
