Radio Doppler log target simulator and simulation method

The invention discloses a radio Doppler log target simulator and a simulation method, and relates to the technical field of ship speed measurement, the radio Doppler log target simulator comprises a host, and the host is connected with a remote control box. According to the invention, the speed information is set in the remote control box, the Doppler effect is utilized to convert the speed information into a frequency offset parameter, and the received radio Doppler log microwave signal is changed and sent to the antenna radio Doppler log for static measurement of the radio Doppler log. 本发明公开了一种无线电多普勒计程仪目标模拟器及模拟方法，涉及舰船测速技术领域，包括主机，所述主机连接远控盒。本发明在远控盒设置的速度信息，利用多普勒效应将速度信息转换成频偏参数，改变接收到无线电多普勒计程仪微波信号，并发送给天线无线电多普勒计程仪，用以静态对无线电多普勒计程仪进行测定。
