FPGA Coprocessor-Based IMM-SDCMKF Application to a Radar Maneuvering Target Tracking System
Authors: , ,
Abstract: This paper presents a maneuvering target tracking system using Interacted Multiple Model-Second Debiased Converted Measurement Kalman Filter (IMM-SDCMKF) based on FPGA coprocessor. IMM-SDCMKF is considered one of the most effective algorithms for maneuvering target tracking. However, the computation of this algorithm is time-cost and complex. The traditional design approach is unable to meet the high-speed real-time signal processing needs. In this tracking system, the FPGA is used as a coprocessor of the DSP, and the large amount of calculation of IMM-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. The experiment results show that the designed scheme meets the high precision and real time of the maneuvering target tracking system.
