 "Jamming" or AECM (Active Electronic Countermeasures) can be broken 
 down to one of two basic goals;
  To overcome the victim radars AGC (Automatic Gain Control) circuitry
  by inducing too much power for the receiver to handle.

  Or to induce false range and/or bearing information into the radar.

  A radar can also be defeated by decoys, such as SRBOC (Super rapid blooming
  offboard chaff) or decoys such as corner reflectors. 

  Aecm works most effectively on radars such as, Missile Guidance, Target
  aquisition or Terminal Homers.
