| 摘 要： | 利用短时傅立叶变换和子波变换的性质，针对两种实际的信号模型，提出了一类基于线性时频子空间匹配投影算法的暂态信号检测方法，推导了它的两种实现形式，并给出了计算机仿真结果。该方法充分利用了信号的先验信息并建立了匹配的信号模型，表现了较好的性能

| Abstract: | In order to solve the problem of detecting two types of actually signal m odels, a kind of optim al detection m ethod w ith fully exploiting structure in the linear tim e-frequency dom ain is presented based on the definition ofshort-tim e fourier transform and wavelettransform theory. Im plem entation w ays fortwo detectors are derived and the num ericalexam ples show thatthe m ethod has outperform ed than thetraditionalones. |
