Air Defense Missile Detonation Delay Control Based on FPGA/DSP
Authors: , ,
Abstract: This paper presents the hardware design of a real time tracking system based on DSP/FPGA regarding the research and air defense missile detonation delay. It is a new trend of missile technology using guidance integrated fuze (GIF) technology to realize optimal burst delay control algorithm. The optimal burst delay control algorithm includes the estimation of time-to-go and miss distance. The paper studied the application of second order debiased converted measurement Kalman (SDCMKF) filer in parameters estimation of burst delay control. In this tracking system, the FPGA is used as a floating point co-processor of the fixed point DSP, and the large amount of calculation of the second order debiased converted measurement Kalman Filter (SDCMKF) algorithm is realized in FPGA. DSP is in charge of the scheduling of the total tracking algorithm and the control of the data stream, which resolves the problem of the concurrency and real time in the realization of the single DSP scheme. The designed tracking system ensures the accuracy of the data processing as well. Simulation results indicate that the application of this algorithm improved the estimation accuracy of burst delay control. The estimation error reduces gradually and tends to be stable with the distance between target and missile shortened.
