e most knowledgable person regarding Naval warfare. understand or cyclestand?.
Thanks. Anyway can you give more info on that??
EW has three branches: Electronic Support Measures (ESM), Electronic Countermeasures (ECM), and Electronic Counter-Counter Measures (ECCM).
Electronic support measures (ESM) search the RF spectrum for emissions and analyze the results to exploit the weapons or sensors involved. Exploitation includes tactical early warning, identification for counterweapon selection and recording to support countermeasures development.
The second major division of Electronic Warfare is ECM, and of the three divisions it is probably the best known. Partly this is because ECM tends to be visualized as "black boxes" that display a visible realization of electronic warfare. Often it appears that if one understands the black boxes, then one has an understanding of ECM, but such an attitude is very narrow because it ignores the two types of ECM: jamming and deception.
Of the two types of electromagnetic radiating systems against which ECM may be employed--either sensors and/or communications systems--enemy sensors receive by far the greatest attention. The primary reasons for this fact are: (1) the enemy sensor system produces an immediate threat, whereas the communications system does not, and (2) the sensor system is usually specifically directed toward the friendly forces, and communications are not.
From a strategic point of view, using ECM against an enemy communications system is questionable, for by so doing the opportunity to gain valuable information by eavesdropping is lost. Tactically, however, it may be very advantageous to jam the enemy communications system in order to cause a breakdown in his battle plan.
Typical electronic sensors against which ECM might be used include long-range passive detectors; radar-warning picket ships; airborne radar patrols (AWACS); long-range early-warning radar sets; ground-controlled intercept radar sets; fighter intercept radar; missiles guided by radar or infrared; radio and radar navigation equipment; electronic bombing equipment; electronic identification equipment (IFF); terrain-following radar; antiaircraft artillery (AAA); fire control radar; and surface-to-air (SAM) control radar, etc. The particular method used will depend upon the tactical situation.
Jamming Tactics.
Self-screening jammers (SSJ)Stand-off jammers (SOJ).Stand-forward jammers (SFJ).
The other major type of active ECM is deception. In contrast to noise jamming, deception tries to mimic the radar echo so that the radar will respond as if it is receiving an echo from another aircraft or ship.
Electronic Counter-Countermeasures (ECCM)
Electronic counter-countermeasures is the art of reducing the effectiveness of an EW threat with the objective of making the cost of effective EW prohibitive for the enemy.
Chapter 11 COUNTERMEASURES
the ship's electronic warfare systems defeated all incoming aircraft by blinding them with directed energy.
INS Vikramaditya has might but little protection against air attacks - Indian Express
While the attacking aircraft would be blinded, the opponent might use its ESM to locate the source of the directed energy (=jamming) from a MPA, ship or shore based installation. As a ship group you maintain EMCON (emissions control), you only start jamming at the point where you come under attack (i.e. after you've been spotted). Jamming helps prevent a succesfull attack (e.g. opposing force's weapons' lock) but it doesn't render your own assets invisible or undetectable.
