Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat.
The AN/ALQ-218 is an airborne passive Radar warning receiver / electronic warfare support measures / electronic signals intelligence (RWR/ESM/ELINT) sensor system designed for airborne situational awareness and signal intelligence gathering. The AN/ALQ-218 detects, identifies, locates and analyzes sources of radio frequency emission.
The AN/ALR-67 countermeasures warning and control system is the standard threat warning system for tactical aircraft and was specifically designed for the A-6E/SWIP, AV-8B, F-14B, F-14D and F/A-18. The system detects, identifies and displays radars and radar-guided weapon systems in the C to J frequency range (about 0.5 to 20 GHz).
Because the external radar causing the transponder to respond is generally not synchronised with your own radar (i.e. different pulse-repetition frequencies), these black dots appear randomly across the display and the operator sees through and around them. The returning image may be much larger than the "dot" or "hole", as it has become known ...

AN/ALQ-153 is an airborne Pulse-doppler tail warning radar for detecting missiles, protecting B-1B Lancer and B-52H Stratofortress aircraft. [ 1 ] [ 2 ] [ 3 ] It replaced the AN/ALQ-127 , introducing a solid-state transmitter, frequency-agile waveform and digital processing using non-scanning antennas that have low backlobes . [ 1 ]
The radar is designed with high resistance to electronic countermeasures (ECM) and anti-radiation missiles (ARM). [ 1 ] The system automatically acquires, tracks, classifies , identifies and reports high- and low-altitude targets, including cruise missiles , unmanned aerial vehicles , and both rotary- and fixed-wing aircraft .
