Abstract

Two typical types of signal model known as narrowband and wideband signal models are frequently used in radar, sonar and communication signal processing. A matched filter in two-dimensional linear time-frequency plane is studied and the optimal signal detection methods based on match projection onto time-frequency and time-scale subspace are presented for the effective detection of these two-type signals. Simulation results show that the methods have good performance and robustness
