Abstract:
In order to improve the system phase noise and ground clutter suppression capability, Burst technology was modified for some domestic CINRAD/SA weather radars to reduce and eliminate the influence of phase jitter of the transmitted signals. To test the improvement of phase noise and ground clutter suppression ability of CINRAD/SA weather radar after Burst technical transformation, the theoretical analysis, performance test and echo data analysis are used to test the capability. The test results show that the phase noise of the CINRAD/SA weather radar system is reduced by about 0.05° after the Burst technical transformation, and the ground clutter suppression capability is improved by more than 55 dB. The phase noise and ground clutter suppression capability are improved obviously, and can be used as a good reference for other models of weather radar.
