Angle tracking technology based on digital channelized large dynamic PCM/FM telemetry signals
The angle tracking technology based on digital channelized large dynamic Pulse Code Modulation/Frequency Modulation(PCM/FM) telemetry signals is presented by using monopulse angle tracking system. PCM/FM signal is a kind of narrowband signal, whereas the Doppler frequency shift is very large, which reaches to ±1MHz. In order to capture and track the narrowband PCM/FM signals accurately in a broad bandwidth and at large Doppler frequency shift, the digital channelized technology is adopted; and all the subsidiary channels are detected at the same time; the data fusion and amplitude detection are performed after the detection; and finally the angle error is estimated. Simulation results show that the proposed method can achieve signal angle tracking fast, efficiently and feasibly.
