Abstract
According to the equipment indexes and based on FFT circulation related algorithm,this paper proposes a spread spectrum Pseudo Noise (PN)code acquisition scheme. Coherent accumulation and Constant False Alarm Rate (CFAR)threshold setting are adopted to improve the scheme. The characteristic analysis of CFAR detection model and choice of times about cyclical accumulation are completed. Implementation frameworks for circulation related module and peak detector module based on Field Programmable Gate Array (FPGA)are designed. Simula-tion and analysis show that the scheme meets practical need and must be of great practical value.关键词
