Relevant problems and simulation analysis on bistatic tracking radar of T-R

Abstract:

Radar plays a great role in electronic antagonizing. The special characteristics of system and key technique problems needed to be solved on bistatic tracking radar of Transmitter-Receiver(T-R) type were analyzed. The time synchronization technique, the frequency synchronization technique and space synchronization technique between transmitter station and receiver station were introduced. The deficiency of traditional single range solving method was analyzed. Then two range solving methods based on adjusting the transmitted spring pulse and received range synchronization pulse were discussed. The time calibration methods on the measure value of bistatic radar were described. Finally the position precision of bistatic radar and the improvement on position precision of range by adopting networking multi-static radar system were studied. The simulation results show that the networked bi-(multi)static radar systems can apparently improve the ranging accuracy near the baseline by data fusion.
