Radar Multi-target Track Correlation Based On DSP

With high-performance digital signal processors DSP and large-scale programmable logic devices appear to radar signals in the digital processing brought about a new breakthrough. In this thesis, Research radar data processing system of multi-target track-correlation treatment based on DSP. Radar data processing system used SD7541A high-speed DSP processing board system constitutes the core of hardware platforms, implement radar data processing through the DSP.SD7541 A board integrates a high-speed A/D, high-performance TMS320C6416DSP and FPGA, and other devices. Radar data processing system is constructed by general DSP, making the system more focuse on the design of software programming .Radar data processing means the radar measurement data to the Internet, tracking, filtering, smoothing, forecasting, and other treatment, can be effective in inhibiting the process of measuring the introduction of random error, accurate estimates of the target location and movement parameters, predicted the next target At the location of the target to form a stable track to achieve the objectives of the high-precision real-time tracking.The major achievements of this thesis are as follows:1. Research of the data correlation algorithms. Data Association is to establish a time measurement data and other measurements, or at the track, to determine whether these measurements with a goal from the process. In this thesis, the author discusses the technology of relevant gate, track classification and the relevant criteria. Moreover, the matching algorithm is given which is suitable for the weak and strong clutter environment.2. Research of the track initiation and track quality management issues. Track initiation and track quality management is a multi-target tracking theory in two important components, is the establishment of new goals and targets to eliminate redundant files essential part of the decision-making. In this paper, in the cluttered environment of the track initiation and track quality management, and gives simulation. 3. Discussion on the construction of the hardware platform of radar data processing system and on the construction of the software framework based on DSP /BIOS realtime operating system.Discuss a multi-target correlation processing program design and optimization, and algorithm processing time for testing and analysis. Algorithm that can meet the test of real-time system requirements.This thesis focus on multi-target track in the track initiation, data association and track quality management, and other issues based on DSP.
