Electronic Countermeasures (ECM)

1989
Because it finds and measures noncooperative targets, radar motivates various countering actions. Motorists might want to deprive the highway patrolman of information about their speed. Certainly, nations want to deny other nations all kinds of information, particularly in times of tension or war.

Waveform optimization for electronic countermeasure technique generation

2008 IEEE Radar Conference, 2008
Recent work on electronic countermeasure (ECM) technique generation employed genetic algorithm optimization methods to define simple range-gate pull-off waveforms against a generic range-tracking radar simulation. This automated approach has potential to greatly reduce technique development time which is traditionally prolonged by manual ...

Maximising the benefits of sophisticated electronic countermeasures systems

IET International Conference on Radar Systems 2007, 2007
As electronic countermeasure systems become more complex, the time taken between the equipment being specified, designed, developed and eventually fielded has lengthened significantly. During this development, advances in radar processing are likely to change the requirements for countermeasure waveforms, and the original specification from which the ...

Autonomously Deciding Countermeasures against Threats in Electronic Warfare Settings

2009 International Conference on Complex, Intelligent and Software Intensive Systems, 2009
This paper investigates the autonomous decision-making process of threat detection, classification, and the selection of alternative countermeasures against threats in electronic warfare settings. We introduce a threat model, which represents a specific threat pattern, and a methodology that compiles the threat into a set of rules using machine ...

Electronic Counter Countermeasures (ECCM)

1998
In the previous chapter, we examined the principal types of electronic countermeasures (ECM). We learned how each type is implemented and what its limitations are. In this chapter, we will examine some of the important electronic counter-countermeasures (ECCM) which have been devised to exploit the limitations of ECM and so defeat them.

Electronic Countermeasure (ECM) Techniques

1998
In this chapter, we will be introduced to the six basic types of countermeasures - chaff, noise jamming, false targets, gate stealers, angle deception, and decoys. We will see how each is used, and learn how it is implemented and what its limitations are.

Integrated Defensive Electronic Countermeasures (IDECM)

2013
Abstract : The Integrated Defensive Electronic Countermeasures (IDECM) System is a Radio Frequency (RF), self-protection electronic countermeasure suite on the F/A-18 aircraft. IDECM improves the survivability of the F/A-18 aircraft against RF guided threats during Air-to-Ground/Surface and Air-to-Air missions.

Corrosion in electronics: Overview of failures and countermeasures

2014
Many field failure returns of electronics are marked as “no failure found”, yet numerous of these failures are likely due to corrosion, since corrosion related failures are not easily detected during subsequent failure analysis. In some cases failures are intermittent and occur because of service life conditions (humidity and contamination) where water

Electronic Countermeasures in the Royal Navy, 1940–45

1995
German development of metric and decimetric pulsed radars in the mid to late 1930s — early deployment of ship and shore-based systems. In December 1939 Royal Navy ships were not equipped to detect possible German use of radar in Battle of River Plate — nor were RAF aircraft in daylight attacks on German warships.
