Abstract :
An approach to spectral line tracking based on the fast Fourier transform (FFT) under low pulse repetition frequency (PRF) is discussed in this paper. Compared with the conventional method of spectral line tracking, it is achieved by modification of pulse repetition interval (PRI) rather than the frequency of the coherent oscillator. Our method can be expressed as center filter tracking and filter center tracking
