Coherent integration method for pulsed Doppler radar

摘要

The coherent integration method receives M coherent pulse bursts as a target return. The pulse has a pulse repetition frequency frn. Each pulse is received coherently and a discrete initial Fourier transform formed in a time interval T. Each pulse is time referenced, and the Doppler assembly of each of the coordinates of ambiguous distance and speed is stored. A discrete Fourier transform is then carried out on all M samples of the burst, and a final detection formed from M points of the discrete Fourier transform.
