1) time-frequency data matrix
时间-频率二维数据矩阵
1.
Doppler frequency compensation can be worked out quickly and accurately according to the distance-velocity information included in time-frequency data matrix,and the main clutter s features of different distance cells that it has almost the same Doppler frequency and occupies several distance cells.
根据时间-频率二维数据矩阵中包含的距离、速度信息,利用不同距离单元的主杂波谱线所处的滤波器号几乎相同,且所占的距离单元数比较多的特点,采用FFT快速数字信号处理算法,实时、准确地得到多普勒频率的补偿值,从而对步进频信号处理中多普勒效应进行补偿。
2) frequency time matrix
频率-时间矩阵
3) two dimensional spread spectrum matrix
