摘要
本文介绍了一种新研制的多功能可编程数字式雷达信号处理机。它包括点数可变的自适应动目标显示(AMTI),数字脉压(DPC),动目标检测器(MTD),数字积累(DI)和恒虚警率处理(CFAR)。系统工作方式和参数可由编程或雷达计算机指令来灵活地选择和改变。机内设有先进的动态自诊断逻辑,可将故障隔离和指示到电路板。测试结果,系统对地杂波的改善因子大于53dB,对气象杂波的改善因子大于40dB,数字脉压的旁瓣电平小于-40dB。由于采用了创新的算法和先进的器件、结构,从而使整机运算速度高达1148MIPS。该系统可配用于各种先进的三座标和两座标雷达。
A multi-function programmable digital radar signal processor which has been developed recently is described. It is composed of adaptive MTI (AMTI) with variable number of pulses, digital pulse compression (DPC), moving target detector (MTD), digital integration (DI) and constant false alarm rate (CFAR). The operation mode and parameters of system can be changed flexibly by programming and instruction from radar computer. The system also contains advanced BITE, which can isolate and detect faults on board. The test results indicate that average improvement factors of the system for ground clutter and weather clutter are greater than 53dB and 40dB respectively. Side-lode of DPC is smaller than -40dB. Since the system uses new algorithm and advanced devices and architecture, the operation speed is up to 1148 MIPS. It can be used in 3-D radar systems and many different surveillance radar systems with high performance.
