在目标作匀加速直线运动的假设条件下，提出了一种基于线性差分方程的运动弱目标检测方法，导出了其信噪比增益的表达式，并分析了速度和加速度失配对信噪比增益的影响。该方法存贮量要求小，并且也利于实时处理。实验证明它有效地解决了低信噪比条件下弱目标的检测问题。
Under the assumption of uniform acceleration and linear motion of the target, a moving target detection method based on linear difference equation is proposed. The expression of signal-to-noise gain is deduced. The effects of velocity and acceleration mismatch on SNR gain Impact. The method requires little storage capacity and is also conducive to real-time processing. Experiments show that it effectively solves the problem of detecting weak targets under low signal-to-noise ratio.
