摘要

在雷达、声纳和通信信号处理中经常使用两种典型的信号模型，即窄带和宽带信号模型。研究了二维线性时频平面上的匹配滤波器，提出了基于匹配投影到时频子空间和时尺度子空间的最优信号检测方法，以有效检测这两种类型的信号。仿真结果表明，该方法具有良好的性能和鲁棒性。

Signal detection based on match projection onto time-frequency and time-scale subspace

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.
