Single-channel single-pulse angle tracking method based on digital signal reconstruction

The invention discloses a single-channel single-pulse angle tracking method based on digital signal reconstruction, and belongs to the technical field of space communication. According to the invention, discontinuous signals on time can be recovered to continuous signals with continuous phases on time. On the basis, a microwave switch is used for replacing a modulation and sum circuit module in a traditional single-channel single-pulse technology, sum and difference signals are alternately gated in a time-sharing mode by controlling the microwave switch, and the sum and difference signals are converted into digital signals after being amplified, down-converted and filtered. In a digital domain, continuous in-phase and orthogonal signals are recovered from intermittent sum signals by adopting the signal reconstruction method disclosed by the invention, and relative amplitude and phase of difference signals are extracted by taking the reconstructed in-phase and orthogonal signals as a reference, so that estimat
