摘　　要：研究了红外多模采集转换的系统模型 ,分析了功能状态。研究了基于并行DSP、数据并行通信芯片和可编程逻辑器件构架的可行性系统实现 ,论证了系统的实时并行处理能力。研究了数字锁相实施玫瑰线扫描同步采集方位转换和红外多帧配准图像模糊分割识别系统实现。实验表明 ,该系统具有 2 5 6× 2 5 6像素场景 ,2 5 6级灰度级实时监测和复杂背景下实时识别目标的能力。System model of the infrared multi-mode acquisition and transform is presented in this paper. Functional states of the system model are analyzed. Feasible system application, which is based on parallel DSP, dual port data-share chip, and programmable logic device, is implemented. The real-time and parallel processing ability of the system is investigated. The phase-lock azimuth transform and infrared registration recognition are implemented in the system. The experiment reveals that the system can realize 256×256 pixel and 256 gray scale supervision in real-time, and it also can fulfill recognition under complex circumstance in real-time.\;
