摘要
论述了 8mm战场侦察雷达信号处理系统的距离估算、参数计算、硬件结构等问题。在距离估算中提出了综合相参积累和非相参积累因素的雷达距离公式。信号处理算法采用流水线结构 ,根据这一特点 ,整个硬件系统采用 6片 ADSP2 10 6 0数字信号处理芯片 ,通过巧妙的连接组合实现了系统所要求完成的算法。通过扩展的串口和并口实现了和天控、计算机的有效连接。
Some problems such as range estimation, parameter calculation, hardware structure for an 8mm battlefield surveillance radar are described in this paper. The range formula in which phase coherent accumulation and non-phase coherent accumulation are considered is derived. The digital signal processing algorithm in this radar involves in pipeline structure.According to this feature, whole hardware system adopts six ADSP21060 digital signal processors. The hardware is so smart that this algorithm is implemented effectively. The digital signal subsystem is connected with antenna control subsystem and a notebook computer by extensive serial port and parallel port respectively.
