虽然在研制电子战接收机的工作中业已开始着手解决探测毫米波雷达的需要,但提供给设计人员的ESM性能数据却很少.洛克希德加拿大公司最近提供了一些数据,至少能部分满足上述要求.他们报道了在28～40GHZ频率范围内的测向(DF)测量结果.他们采用常规单脉冲技术,结合高截获概率技术和大瞬时动态范围,利用野外测试场,获得了5°～6°RMS的DF精度.用一个圆型多端口DF阵最直接进行了单脉冲测向,接收机每截获一个脉冲便产生一个数字脉冲描述字输出,包括脉宽、方位、幅度,到达时间和频段.
While ESM receivers are already beginning to address the need to probe millimeter-wave radars, there is very little ESM performance data available to designers. Lockheed Canada recently provided some data that could at least partially satisfy the above They reported DF measurements in the frequency range of 28-40 GHz using a conventional single pulse technique combined with high interception probability techniques and large transient dynamic range using field test fields to obtain a 5 ° to 6 ° ° RMS DF accuracy The most direct monopulse direction finding is done with a circular multiport DF array. The receiver produces a digital pulse descriptor output per intercept pulse, including pulse width, azimuth, amplitude, arrival time and frequency band .
