Study on clutter modeling and computer simulation of PD fuze

The ground clutter and sea clutter has a significant impact on aerial defense missile, which is mostly working in the look down mode [M. Diani et al., April 1996]. It is necessary to analyze the clutter jamming on fuze and to enhance the jam proof ability. In this paper, according to the working characteristic of the pulse Doppler (PD) radio fuze, we study and build up the clutter model and bring forward an analysis method of clutter signal intensity in the cell of fuze distance-Doppler frequency, and also give an example to explain the method. Finally, the validity of the method has been proved by the simulation results.
