  • A joint range-velocity closed loop tracking filter, where velocity measured value is adopted in the range tracking filter to modify the velocity and acceleration equations, is proposed. The tracking loop use the proposed filter can not only track the range and velocity simultaneously, but also improve the range tracking precision significantly. The experimental results show that the tracking errors about range thermal noise in the proposed loop is lower than that in the traditional loop over 2.2dB. Moreover, with the increase of the filter parameter, the tracking performance of our schemes are improved accordingly.
