The RSA solved this by using a second radio signal for beam riding, allowing the tracking radar to have a wider search angle without effecting the accuracy of the missile.
22.
Another disadvantage of any beam riding system is that it is not possible to " lead " the target, and it is thus suitable only for slow targets or very short distances.
23.
Although radar beam riding guidance was planned to solve this, The test program was considered to be successful despite this, as a considerable amount of knowledge was gained that benefited later programs.
24.
The LMMs in the initial batch use laser beam riding with infrared terminal homing and a laser proximity sensor, although a semi-active laser version is under development for precision surface attack roles.
25.
The steel beams ride lower inside the underbody of the Mercedes, with the front cross-beam just 19.5 inches high, even though the overall vehicle still has the same ground clearance as other sport utility vehicles.

The missile has often been confused in the west with the 9A1472 Vikhr dual-purpose laser beam riding missile used on the Kamov helicopters and Sukhoi attack aircraft ( as well as some Ukrainian Mi-24 / 35 upgrades ).
28.
This means that the beam riding system is not accurate at long ranges, while SARH is largely independent of range and grows more accurate as it approaches the target, or the source of the reflected signal it listens for.
29.
Contrast this with beam riding systems, like the RIM-8 Talos, in which the radar is pointed at the target and the missile keeps itself centered in the beam by listening to the signal at the rear of the missile body.
30.
Targeting is by search radar and beam transmitter with targets tracked by a search radar until a beam riding transmitter locks on, at which point the missile can be fired, riding the beam until impact, proximity fuze or radio signal detonation.
