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.
The Ground Master 200 Multi-Mission (GM200 MM) is a family of medium-range radars manufactured by Thales Nederland. [1] [2] Benifiting from the technology of the land-based Ground Master 200 and naval NS100/200 radar systems, this series was developed by the Dutch subsidiary for, and in consultation with, the Royal Netherlands Army (RNLA).

Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
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.
Aselsan EIRS (Early Warning RADAR System) is a new generation S-Band radar, developed for long range early warning purposes, with AESA and digital beamforming antenna architecture. The system developed by Turkish company Aselsan. In addition to air-breathing air targets, EIRS also has the ability to detect and track Ballistic Missiles and ...
A pencil-beam radar A moving or sweeping pencil-beam radar. In optics, a pencil or pencil of rays, also known as a pencil beam or narrow beam, is a geometric construct (pencil of half-lines) used to describe a beam or portion of a beam of electromagnetic radiation or charged particles, typically in the form of a cone or cylinder.
In the UK, the evidence is admissible in court using the speed measured by the radar. The speed calculated from the distance travelled between the photographs using the secondary check mark white lines is used by police forces to verify the radar reading, and can be used as a defence in the event of an unreliable reading by the radar.
