Radar Electronic Counter-Countermeasures

A Mini Review on Radar Fundamentals and Concept of Jamming

“…Electronic Counter Measures (ECM) is that division of electronic warfare involving actions taken to prevent or reduce an enemy's effective use of the electromagnetic Spectrum [3,4]. Radar Jamming is an Electronic Counter Measure (ECM) technique to prevent, delay, or confuse the Radar processing of target information.…”

Introduction to electronic warfare

“…Radar ECCM techniques [19] normally exploit some form of signal agility to confuse the intercept receiver. PRI agility is the simplest technique which complicates the pulse-sort processor, while agility of the transmitted frequency necessitates wideband wide-open intercept-receiver designs, or very complex signal-analysis techniques.…”

“…Electronic counter-countermeasures [19] are employed when experiencing interference from enemy ECM or from friendly transmissions, i.e. an environment of poor electromagnetic compatibility (EMC) between equipments.…”

“…Many established signal-processing techniques [18,19,76] are also relevant in ECCM. For example, radar MTI filtering can be applied to separate slow moving chaff from a fast moving target.…”

“…Many other techniques [19] are relevant to providing ECCM capability. One notable recent development in particular is the deployment of bistatic radar [18,44].…”
