Study on Advancing the Performance of Velocity Compensation for Stepped Frequency Radar

The target radial motion made the stepped frequency pulse echo deformed and the accuracy of the time domain cross correlation method was not satisfied with the demand. For solving this problem the advanced time domain cross correlation method was put forward. Under the condition of few sample points this method could reduce the searching range based on preliminary velocity estimation value and compensation accuracy value. So this method was satisfied with the demand of accuracy. The simulation results and performance analysis manifested this method processed the stability, small calculation, convenient for real-time processing, and the application value was higher.
