机载雷达接收的杂波回波呈现出具有多普勒带宽，这个带宽取决于平台速度、波束宽度和波长．因此，慢速目标的回波可能会隐藏在杂波频带内以致难于检测。由于飞机的飞行动态特性以及风力影响引起飞行路径的扰动会进一步降低ＭＴＩ的性能。从早期研究者的论文中已证明，线性阵列天线的输出信号端接上空域时域ＦＩＲ滤波器可以自适应补偿平台运动的飞行路径分量，从而大大提高了信号与杂波加噪声之比（ＳＣＮＲ）。这种滤波器是指ＴＡＳＴＥ（机载慢速目标的提取技术）方法。本文将这种思路加以推广，用一个水平方向的平面阵列来补偿横向速度分量。并研究了系统的带宽效应．得出的结论可推广用于没有惯性导航器件的情况下对飞行路径的三维扰动补偿。
The clutter echo received by an airborne radar appears to have Doppler bandwidth, which depends on the platform speed, beam width and wavelength. Therefore, echoes of slow targets may be hidden in the clutter band and so difficult to detect. MTI performance is further reduced due to the flight dynamics of the aircraft and disturbances in the flight path due to wind effects. From the early researchers’ paper, it has been proved that the output signal of the linear array antenna can be adaptively compensated for the flight path component of the platform motion by connecting to the spatial domain FIR filter, thereby greatly improving the signal-to-clutter plus noise ratio (SCNR ). This filter is TASTE (airborne slow target extraction technology) method. This article will be to promote this idea, with a horizontal plane array to compensate for horizontal velocity components. And studied the system’s bandwidth effect. The conclusion can be generalized to the three-dimensional disturbance compensation of flight path in the absence of inertial navigation device.
