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 ...
The final service version, the mod 3, was a true semi-active radar homing (SARH) missile with a continuous-wave radar receiver built into the missile, which homed in on the CW radar return of the illumination radar. This CW return, reflected from the target, would be scattered in all directions however the closer the missile came to the target ...
This problem is avoided in the semi-active radar homing (SARH) concept. In these systems, the ground station still illuminates the target with its radar, but the receiver is on the missile. The reflection of the original signal off the target produces another cone-like beam, but one that is narrowest at the target.
This model also featured new 5V55R missiles, which increased the maximum engagement range to 75 km (47 mi) and introduced a terminal semi-active radar homing (SARH) guidance mode. [15] [16] The surveillance radar of these systems was designated 30N6. Also introduced with this version was the distinction between self-propelled and towed TELs.
command guidance with terminal semi-active radar homing (SARH) The 2K12 "Kub" ( Russian : 2К12 Куб ; English: ' cube ') ( NATO reporting name : SA-6 "Gainful" ) mobile surface-to-air missile system is a Soviet low to medium-level air defence system designed to protect ground forces from air attack.
In this role, these are known as "midcourse guidance" systems. In practice, terminal guidance systems are often optical or active radar systems, in an effort to greatly increase accuracy. These systems often have many times the accuracy of solutions like SARH, but operate only at short ranges, on the order of a few kilometers.
The AN/SPG-55 was an American tracking / illumination radar for Terrier and RIM-67 Standard missiles (SM-1ER/SM-2ER). It was used for target tracking and surface-to-air missile guidance as part of the Mk 76 missile fire control system. [4] It was controlled by a UNIVAC 1218 computer.
'Thunderbolt-11') is a medium-range semi-active radar homing (SARH) air-to-air missile (AAM) developed by a subsidiary of the Shanghai Academy of Spaceflight Technology in the People's Republic of China. It is a derivate or copy of the Italian Aspide air-to-air missile, which in turn was developed from the American AIM-7 Sparrow. PL-11 is not ...
