针对被动毫米波技术探测高速运动目标能力不足的问题，采用 MMIC 直接检波式毫米波辐射计，构建了被动毫米波探测系统，通过试验获得了不同条件下的实测数据。在对测试信号的特征进行分析的基础上，指出第一脉冲的峰值和两峰值脉冲的间距是能够反映目标运动特性的有效特征，提出了计算目标运动速度的方法。计算结果表明，该方法具有一定的精度，在被动毫米波系统中确定运动目标参数是可行的。

To solve the problem of insufficient ability when detecting the high-speed moving target with passive millimeter wave technology ,a direct-detection passive millimeter wave detecting system using the monolithic microwave integrated cir -cuit (MMIC) millimeter wave radiometer is built ,and the measured data are obtained by experiment under different condi -tions .Based on feature analysis of testing signals ,it points out that the peak of the first pulse and interval of two peak pulses are valid features which can reflect the motion characteristic of target .A method to calculate the moving speed of target is put forward .The calculating results indicate that the proposed method has enough accuracy and is feasible to determine the parameters of the moving target using for passive millimeter wave system .
