1.5 Direction Finding (DF) and Emitter Location 测向与定位 Of special importance to operational ELINT (OPELINT) is the location of emitters. This is usually approached by means of angle-of-arrival (AOA) measurements for coarse location and also for pulse sorti ...
1.4 Probability of Intercept Problems 截获概率 The ELINT receiver has an advantage in the versus path loss over the radar. However, the ELINT operator usually does no ...
1.3 Limitations Due to Noise 噪声对 ELINT 接收机的限制 Although in the usual situation the intercept receiver enjoys a considerable range advantage over the radar, this does not mean that the ELINT signal analyst has the luxury of a high signal-to-noise ratio (SNR). The sit ...
1.2 The Importance of Intercepting and Analyzing Radar Signals 截获并分析雷达信号的重要性 The first large-scale use of radar occurred in World War II. No sooner had radar been deployed (by both sides) than the effort to counter it spawned electronic countermeasures (ECM), which include ...
