The motion model and measuring model of maneuvering target are established in airborne PD Radar system, and then Kalman tracking filtering algorithm is also elaborated on. 3 processor structure is introduced to realize the 4 dimension (i.e. distance, speed, azimuth and elevation) tracking experiment system. In the end, error curve is figured. The experiment results show that Kalman filtering algorithm,with the characteristic of high tracking precision and great amounts of computation, can be implemented in real time processing by using DSP technology.
