Design And Implement Of Missile Fuse Signal Processor Based On DBF Technique

Based on the theory of DBF (Digital Beam Forming) and the background of the application of the missile fuse, this article introduced the algorithms of DBF and the hardware frame of the signal processor of the missile fuse. The major work and contribution of this article are as follows:Firstly, this paper introduced the basic concepts and the application background of the technology of DBF in detail, and analyzed the primary algorithms of DBF. Also, it introduced the design method about the hardware frame of the signal processor of the missile fuse, and realized the whole hardware frame.Secondary, each module of the hardware design was introduced. The hardware system consisted of the four parts, which was base-band signal generator module, the echo signal gathering module, the control module and the power module. The hardware design adopted the idea of the synchronization of FPGA and DSP, and realized the connection of high-speed ADC, DAC, and buffer of pulse through FPGA. As a result, it speeded the algorithm and the efficiency of working.Thirdly, This article put emphases on the signal processing algorithms based on DBF technology, System's algorithms was simulated on Matlab platform. Also, it carried out on FPGA platform. This article put forward a new LMS algorithm. In FPGA design, main focus was drew on the implementation of M sequence, FFT and Fir filter.
