Rho-Theta methodology is a key component in Area Navigation (RNAV). [1] The term "Rho-Theta" consists of the two Greek letters corresponding to Rho and Theta: [2] [3] [4] Rho (Greek ρ) as a synonym for distance measurement, e.g. Rho would be the equivalent to the English abbreviation "R" for Range
Beam riding is one of the simplest methods of missile guidance using a radar. It was widely used for surface-to-air missiles in the post-World War II era for this reason. An early example was the British Brakemine, first tested in 1944, as was the first commercially available SAM, the Oerlikon Contraves RSA.
An object at height h above the ground and slant range R forms an angle α that can be calculated through sin α = h / R.By re-arrangement, R = h / sin α, or R = h csc α. The radar equation states that the signal received from an object, P e, varies inversely with the 4th power of range and directly as the square of the antenna gain, G, such that P e ~ G 2 / R 4.
A blind approach beacon system or beam approach beacon system (BABS) is an automatic radar landing system developed in the early 1940s. [1] It is a responder (or transponder) mounted in a Hillman van and placed at the end of the runway. In some cases fixed sites were installed and by the mid-1950s Standard 9 vans were in use.
Conical scanning concept. The radar beam is rotated in a small circle around the "boresight" axis, which is pointed at the target. Conical scanning is a system used in early radar units to improve their accuracy, as well as making it easier to steer the antenna properly to point at a target.
This is a List of Beam Approach beacon system Units of the Royal Air Force. The first system to guide RAF aircraft safely down onto a runway was called the Standard Blind Approach (SBA) system and was trialled in the late 1930s. It was also being used by a few civil airports.
The system has two operating modes: medium range up to 150 km (81 nmi) at 27 RPM and long range up to 250 km (130 nmi) at 13.5 RPM. The radar mainly designed for light frigates, corvettes and ships such as Landing Platform Docks (LPD). SMART-S Mk2 is designed to support full performance of surface to air missiles (SAM), such as the RIM-162 ESSM.
Beam steering is a technique for changing the direction of the main lobe of a radiation pattern. In radio and radar systems, beam steering may be accomplished by switching the antenna elements or by changing the relative phases of the RF signals driving the elements. As a result, this directs the transmit signal towards an intended receiver.
