Anti-radiation / Tv Imaging Dual-mode Seeker Guidance Technology Research

Research about Anti-Radar missile having AR/TV double-model is a new~. advanced subject. Above all, the double-model information fusion and guidance law are the key technique for that research and the goal in this paper is mainly to discuss the two key techniques. The main contents are summarized as follows: 1. Guidance law for this missile have been put forward. Guidance algorithm for the ARM is an application of proportional navigation and modem control theory. The main advantage of using modem control theory is the ability to design the guidance law so that it minimizes a performance index. The significance of this is that the performance index can be chosen to reflect the mission requirements. The derivation of the guidance law and the means of implementing the algoritluns have been shown. The simulated results show that the multiple guidance law prior to a proportional guidance law. 2. A kind of data fusion of double-model controling and guiding system is established. Then a signal detecting methodata target identification method based on Bayes reasoning technology and D-S evidence theory are brought forward to fuse data. The simulated results demonstrate that the feasibility of the methods for data fusion is very good, and D-S evidence theory has the superiority to Bayes reasoning technology. In a word, the scheme brought forth in this paper has the ability to reduce the miss distance and to raise the degree of accuracy; and has resistance to jam and Turn-off radar.
