The study on the Ka-band tracking receiver

In order to capture the signal of low orbit high-speed cooperation targets by using Ka-band antenna, the scheme that S-band antenna is used for guiding, and Ka-band antenna is used for tracking. In this paper, a single channel monopulse Ka-band tracking receiver is given, which is suitable to this scheme. The working principle of this receiver is that the difference channel BPSK modulated works together with the sum channel to track the target. The tracking error of the Ka-band receiver is also simulated in Simulink, the simulation result shows that the tracking currency of the Ka-band receiver is suitable to apply.
