1.9 The Impact of LPI Radar on ELINT 低截获概率雷达对 ELINT 的影响 Since ELINT has such value, a natural direction for radar design would be to reduce the ability of a would-be listener to receive the radar signal. Such radar systems are said to have low proba ...
1.8 Major ELINT Signal Parameters ELINT 信号的主要参数 The typical radar signal can be analyzed according to its power (Chapter 7), antenna (Chapters 8 and 10), and carrier modulation characteristics (Chapter 14). There are many receiver characteristics ...
1.7 Receivers for Radar Interception 用于截获雷达信号的接收机 The subject of intercept receivers is quite broad because there is no single design or type appropriate for all uses. Generally, intercept receivers can be divided into warning receivers and ELINT ...
1.6 Inferring Radar Capabilities from Observed Signal Parameters 从测量参数推断雷达性能 The basic function of ELINT is to determine the capabilities of the radar, so that decisions can be made as to what threat it poses. Radar functions are generally to make measu ...
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 ...
