Due to the narrow beam width of Ka-band telemetry equipment, it is difficult to track high-speed flying targets. Through the analysis of the tracking requirements of telemetry equipment, the application of feedforward compound control in telemetry equipment tracking is studied, and the reasonable value of open-loop gain in feedforward compound control is calculated in this paper. The tracking delay problem when tracking the high-speed flying Ka-band target is solved, the time of target acquisition is shorten, and the ability of the equipment to capture and track the target smoothly is improved.
