【 摘 要 】

References(9)Cited-By(1)A new type full digital ultra high frequency (UHF) radar system has been developed by Wuhan University to measure inshore wave. There is no analog mixer and local oscillator (LO) signal generator in the new system, Radio frequency (RF) is directly sampled, the pulse compression is fully completed in digital domain. The system operates at 340MHz with a widely frequency modulated (FM) bandwidth of 15MHz. Average transmit power is about 25 watts, and the maximum range over seawater will be more than 4 kilometers. The results of the field experiment on the coast of East China Sea presented here prove the feasibility of this system.
