The Design of DSP/FPGA based Maneuvering Target Tracking System
Authors: , ,
Abstract: Debiased converted measurement Kalman filter based IMM (IMM-DCMKF) algorithm is a commonly used maneuvering target tracking algorithm, which is combined with the interacting multiple model (IMM) and the debiased converted measurements Kalman filter (DCMKF). However, the computation complexity of this algorithm is large and the traditional realization of this algorithm using software can’t meet the real-time needs in actual application. This paper presents the hardware design of IMM-DCMKF algorithm based on DSP/FPGA. 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 IMM-DCMKF 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 simulations of results which show the hardware design scheme of IMM-DCMKF algorithm can meet the real-time requirement and simultaneously ensure the accuracy of the data processing.
