General description
The function of monopulse tracking receiver is to complete signal amplification, sampling, AGC control, Doppler presetting, frequency guidance, anti-side band error lock, carrier acquisition and tracking. Monopulse tracking receiver mainly includes IF receiving unit and monitoring processing unit. It can accept local or remote control, and can also display the device status locally and report to the remote monitoring device. The test computer can set and monitor the device through the network interface. The receiver is widely used in the tracking subsystem of antenna and coordinating the servo to complete the automatic tracking of the target.
