基于 AD9059的毫米波主被动复合探测器信号处理系统设计

摘要

针对毫米波主被动复合探测器主被动信号的差异问题，鉴于传统双AD芯片分别采样主被动信号，电路设计复杂，提出一种使用单一AD芯片的信号处理系统设计方法。使用AD9059采样主被动信号，并以TMS320 VC5410为核心进行信号处理，实现对目标的测距和识别。该系统不仅设计简单，还具有干扰小、稳定性好、易小型化等优点。目标探测实验表明，该设计能够满足探测器的指标要求，能够很好的完成距离测量和目标识别等探测任务。%This paper proposes a design method of signal processing system using single AD chip based on traditional double AD chip sampling active-passive composite signal respectively to solve the differences of active -passive composite signal in milli-meter wave active-passive composite detector , avoiding the complexity design of circuit .AD9059 with TMS320VC5410 as the core to process signal is used to sample active -passive signal to realize target ranging and recognition .The advantage of this system is simple in design, little interference, good stability and miniaturization.The result of target detection experiment shows that the de-sign can meet the requirement of probe index and complete detection task of target range and recognition .
