In Germany, at least a 3 km/h tolerance (3% of measured speed when speeding over 100 km/h) in favor of the offender is always deducted. This tolerance can increase up to 20% depending on the method of measurement. [52] Fines for speeding depend on how high above the speed limit the measured speed is and where the offense occurred.
The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor. Some weather radars uses doppler shift to measure wind speeds and dual-polarization for identification of types of precipitations. [3] [4] Weather radar; Wind profilers; Millimetre cloud radar ...
In jurisdictions which use a point system, the police or licensing authorities maintain a record of the demerit points accumulated by each driver. Traffic offenses, such as speeding or disobeying traffic signals, are each assigned a certain number of points, and when a driver is determined to be guilty of a particular offence, the corresponding number of points are added to the driver's total.
Steered beam radars steer a narrow beam through a scan pattern to build a 3-D picture. Examples include NEXRAD Doppler weather radar (which uses a parabolic dish) and the AN/SPY-1 passive electronically scanned array radar employed by the Ticonderoga class of guided missile cruisers and other ships so equipped with the Aegis Combat System.
Different radar artifacts cluttering the radar display. Clutter [1] [2] is the unwanted return (echoes) in electronic systems, particularly in reference to radars.Such echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, and can cause serious performance issues with radar systems.
The monopulse radar Cyrano I is located in the nose of the aircraft, in a pressurized enclosure. The antenna, with a diameter of 0.36 m, is movable in both Inclination and azimuth, using servo mechanisms. It includes a transmitter and a receiver. The transmitter, with a peak power of 300 kW in the band (λ = 3 cm), is a 4J 50 type magnetron.

SLC-2 Radar of Bangladesh Army. SLC-2 radar can also be applied in adjusting firing of friendly weapons or rockets. With slight modification to software parameters the radar can also be used to detect and track low flying targets such as light aircraft, helicopters and RPVs. SLC-2 systems have sometimes been mounted on a Dongfeng EQ2102 3.5 ton ...
