echo mode
解釋
回顯方式-
Since the echo signals are partly received, this radar system has detected the target adopting the processing mode of blocking echo signal before and after, and the problems of the isolation between transmitter and receiver and blind range are solved
該體制雷達採用前後截斷回波信號處理方式，當接收部分回波信號后就對目標進行檢測，解決了收發隔離和盲距問題。 -
Professional lavel 24 bit dsp reverberation echo clrcie 4 types of singing mode cound be selected
