Abstract :
The imaging laser radar is fine measure equipment for TAN with the ability to get the high precision 3D terrain. A 3D terrain matching processor was needed to be designed for the specifical application. In this paper, base on the specialty of the imaging laser radar, the3D terrain matching processor was designed, with scheme of DSP+FPGA calculating engine, multi-level memory system, flexible parallel architecture, and FPGA-embedded accelerators. A parallel correlating accelerator base on 2D modular systolic array and other structures were designed to improve the system performance in FPGA. In the end, with strictly abiding the rules of high-speed circuit designing, the detail physical implement was drawn out. The experiments showed that the system could work well in the harsh military environment with high real-time, high reliability, and flexible architecture.
