提出了一种改进型的动目标检测(MTD)跟踪目标设计,该方法可根据目标速度实时计算信号周期,保持目标回波始终位于非关断滤波器内,通过参数设计控制目标回波的频谱远离关断滤波器,保证目标回波信号始终被检测到,MTD 处理方法又可实时测量目标的速度,形成闭环的自适应周期MTD 跟踪。该方法在某型雷达上得到应用,性能良好。

In this paper, an improved (moving targets detection) a MTD tracking target design is proposed. By this method, the signal period is calculated in real time according to the target velocity, keeping the target echo in the non-OFF filter; and by parameter design, the spectrum of the target echo is controlled to be faraway from the OFF filter so as to ensure the echosignals always being detected. Meanwhile, MTD processing method can measure the velocity of the target in real time, forming a closed loop adaptive period MTD tracking. The method has been applied on a type of radar and has good performance.
