The T/R module sensor includes one transmitter and four receivers (1 ×4 format),which are arrayed in the target system. By testing Doppler frequency shifts induced by moving body,the relative space locus of the moving body to the target system can be obtained. So the miss target parameters (distance and direction) will be known. As a telemetering sensor,the fabricated T/R module is an important part of vector miss target parameter testing system. The module adopts FM-CW Doppler radar system. The L-band FM-CW transmitter's output power is more than 1 Watt. The receiver,with sensitivity of better than - 120 dBm,is com-posed of low noise amplifier,coherent receiving mixer, selective IF amplifier, syn-chronous detector and active filter circuits. The T/R module (1 × 4 format)weighs 3 kg,and its power dissipation is 12 Watts and detective range is 50 m.

敏感头T/R组件利用一套发射机和四套接收机(简称1×4结构)在靶标上作面阵配置,通过对运动物体产生的多普勒频率测试处理,可及时获得运动物体相对靶标系统的空中轨迹。从而得到脱靶参数(距离和方向)即脱靶量的矢量位置。已研制成功的这套T/R组件是矢量脱靶参数测试系统中的核心部件──遥测敏感头。组件采用调频连续波多普勒雷达体制。工作在L波段的调频发射机输出1W功率。接收机采用相干接收、选颁中放、同步检波、有源滤波等电路,灵敏度为-120dBm。全套组件(1×4结构)重量3kg,功耗12W,探测距离50m,模拟试验已获成功。
