Modern radars generally perform all of these MTI techniques as part of a wider suite of signal processing being carried out by digital signal processors. MTI may be specialized in terms of the type of clutter and environment: airborne MTI (AMTI), ground MTI (GMTI), etc., or may be combined mode: stationary and moving target indication (SMTI).
Space-time adaptive processing (STAP) is a signal processing technique most commonly used in radar systems. It involves adaptive array processing algorithms to aid in target detection. Radar signal processing benefits from STAP in areas where interference is a problem (i.e. ground clutter, jamming, etc.). Through careful application of STAP, it ...
Data is extracted and recorded from the radar system while aircraft, balloons, ships, drones, missiles or other objects are moved within the radar envelope. The recorded data is compared to distance, altitude, and speed of the objects to evaluate the pass-fail criteria. These are the typical shapes of the physical radar envelope. Flattened donut
R8 Radar/Laser Detector. The R8 is Uniden's top-of-the-line offering. It can identify threats coming from all four directions thanks to its dual antenna, and you get notified via voice alerts.
Radar scalloping for MTI radar begins to become a concern when the radial velocity is greater than the following value. V e l o c i t y > 0.5 × ( C 2 × P e r i o d B e t w e e n P u l s e s × T r a n s m i t F r e q u e n c y ) {\displaystyle Velocity>0.5\times \left({\frac {C}{2\times PeriodBetweenPulses\times TransmitFrequency}}\right)}
DFR7. This low-cost detector has impressive range and all the requisite features, including GPS for low-speed false-alert muting, manual marking of up to 100 known radar locations, and speed ...
An early radar detector Car radar detector (Japanese) A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding.
Fluctuation loss is an effect seen in radar systems as the target object moves or changes its orientation relative to the radar system. It was extensively studied during the 1950s by Peter Swerling, who introduced the Swerling models to allow the effect to be simulated.
