Method Of Distance Precision For Millimeter Wave Fuze In Strong Clutter Background

This master dissertation research paper is intended to meet the needs of effective combat operations against fourth generation reactive armor of tandem warhead system, that solve the problem of accurate distance precision in a low trajectory environment. Analysing common types of ground clutter and characteristic of Continuous Wave Doppler Fuze’s echo, The plan of distance precision for fuze is made. Through tests of target features in different clutter background and data analysing, theory foundation is built for signal processing method. Through simulation and design of feature circuits and debug, The circuits to extract target feature under strong clutter background and distance precision using millimeter wave is completed. Based on target feature testing data, the controlling method for distance precision is modelled and simulated using Matlab with different echo signal. Choosing the proper micro-processor for signal, the hardware of method is achieved. The sample of signal processor that fit for strong clutter background using millimeter is completed. The semi-physical simulation and gun-launch experiments in shoot range shows that this signal processor has a good ability of distance precision,that provides technology support for new type of tandem warhead of tanker gun to destroy armor.
