| Abstract: |
| The phase error of UWBR(Ultra_WideBand Radar) system based on LFM signal, will affect the result of the pulse compression of the radar system. The phase gradient algorithm presented in this paper can estimate the phase error of the system effectively, and improve the performance of the pulse compression. |
| Keywords: phase gradient(PG) pulse compression LFM signal |
