摘要
Abstract
In order to counter the pulse compression radar, using the digital radio frequency memory (DRFM) to sample, store and reproduce the pulse compression signals has become an important means. In allusion to the disadvantages in dealing with the chirp signals with the classical signal processing methods such as time-domain analysis and frequency-domain analysis, this paper introduces short time fourie transform (STFT) into non-stationary signal analysis on DRFM signals. Simulation results show that the method is effective to detect the chirp signals.关键词
