| Terminal sensitive projectile(TSP) sensor system uses MMW/IR sensitive manner, because of the modern warfare has becoming more diversity and complexity, only for carrying on deeper study of multimode composite detection technology of TSP, the comprehensive advantages of the composite detection system can be better played, the target acquisitionã€tracking〠recognition ability of TSP can be enhanced, so that it can fulfill the task better in the bad battlefield environment.In this paper, according to the existing structural characteristics and working process of TSP, based on the MMW/IR composite detection technology, the compound detection signal processing and data fusion technology of TSP has been research. First, analysis the detective data obtained by tower cast experiment, including wavelet decomposition and signal de-noising, gained the ideal waveform without interference state; Secondly, created the signal detection model, finished the simulation of the detection signal waveform characteristics, by using the fuzzy recognition and support vector machine method, completed the identification of true and false targets; Finally, according to the working process of composite detector, design the suitable program and establish the model of data fusion. By analyzing the advantages and disadvantages of commonly used algorithms, choose D-S evidence theory method and two improved program completed the data fusion work of the composite detector, the results show that the detection probability data obtained after fusion is better than the detection probability data obtained by single detector.By the comprehensive treatment of TSP’s information provided by MMW/IR sensor, more reliable judgments and decisions than single sensor can be got, so that the TSP detection system can access a greater degree of information about goals and environments, that greatly enhanced the anti-jamming capability, and can be better adapted to the changing battlefield environment and objective. |
