BAT radar guided bomb RBS-15F anti-ship missile (on right) under the wing of a JAS 39 Gripen fighter, 2007 Active radar homing missile seeker. Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a receiver) and the electronics necessary for it to find and track its target autonomously.
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external ("offboard") source—as it reflects off the target [1] [2] (in contrast to active radar homing, which ...
As jammers proliferated, a number of existing ARMs such as the AGM-88 HARM was modified to also target jammers as the source of radiation. [2] Jammers also led to the addition of a home-on-jam feature to missiles that usually use a different targeting mode (e.g. active radar homing, semi-active radar homing, GPS), allowing them to switch to an anti-radiation targeting mode when radar ...
Prior to the advent of active radar homing missiles the code "Fox three" referred to the use of guns or cannon, such as the M61 Vulcan which is used in various military aircraft. The difference can be noted in various war films, notably in the 1986 film Top Gun , where the term is used in various dogfight scenes.
This leads to one of the most common types of radar-based missile guidance, semi-active radar homing, or SARH. This places a small receiver in the nose of the missile that listens for the signals reflected off the target, and therefore grows more accurate and powerful as the missile approaches the target.

This combined both a radar transmitter and receiver in the missile, making it unnecessary for the pilot to keep the aircraft aimed at the target after firing the missile, [18] unlike Semi-active radar homing (SARH) missiles which require continuous radar-assisted guidance throughout flight. This allowed the aircraft that fired the AAM-N-3 to ...
The Mitsubishi AAM-4 (Type 99 air-to-air missile, 99式空対空誘導弾 (99 Shiki Kūtaikū Yūdōdan)) is a medium-range active radar homing air-to-air missile. It is a modern beyond-visual-range missile developed in Japan and intended to replace the semi-active radar homing AIM-7 Sparrow missile in service. It has been operational since 1999.
