The F-14 D Tomcat incorporates a Hughes AN/APG-71 radar, that is a major upgrade to the AN/AWG-9 system and was initially referred to as the AN/AWG-9 Block V. The transmit and receive portion of the AN/APG-71 is basically a digital version of the AN/AWG-9, but represents a reworking of virtually every part of the system.
The new radar includes a low-side-lobe array antenna, digital scan control, monopulse tracking, frequency agility, and improved signal processing capabilities. Only the transmitter, power supply, and aft cockpit tactical information display are retained from the AWG-9. Reliability is doubled and detection and tracking ranges are increased by 40%. Many of the lessons learned from developing the USAF’s MSIP-II F-15 AN/APG-70 radar set were incorporated into the AN/APG-71. […]
