Time-frequency Filtering and Its Application in Chirp Signal Detection
Time-frequency filtering has been widely used in various applications. In this paper, the timefrequency filtering is applied to the LPP-Hough transform (LHT) which is a method for chirp signal detection. Chirp signals corrupted by heavy Gaussian noises and impulsive noises are considered in the simulations. It shows that the time-frequency filtering can help to greatly minimize the computation complexity of the LHT for chirp signal detection without deteriorating the detection performance.
