Because the external radar causing the transponder to respond is generally not synchronised with your own radar (i.e. different pulse-repetition frequencies), these black dots appear randomly across the display and the operator sees through and around them. The returning image may be much larger than the "dot" or "hole", as it has become known ...
Pulse Doppler radar may have 50 or more pulses between the radar and the reflector. Pulse Doppler relies on medium pulse repetition frequency (PRF) from about 3 kHz to 30 kHz. Each transmit pulse is separated by 5 km to 50 km distance. Range and speed of the target are folded by a modulo operation produced by the sampling process.
A popular example is displaced phase center antenna (DPCA), which is a form of data-independent STAP in the beamspace, pre-Doppler. [7] The goal is to perform beamforming such that the beam appears stationary as the airborne radar is in motion over discrete time periods so the clutter appears without Doppler. [2]
A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity.
A radar tracker is a component of a radar system, or an associated command and control (C2) system, that associates consecutive radar observations of the same target into tracks. It is particularly useful when the radar system is reporting data from several different targets or when it is necessary to combine the data from several different ...
Robin Radar Systems is a European-based defense and technology company founded in 2010. According to the company website, “Robin” is an acronym that stands for Radar Observation of Bird Intensity.
Android Team Awareness Kit (ATAK) is an Android smartphone geospatial infrastructure and military situation awareness app. It allows for precision targeting, surrounding land formation intelligence, situational awareness, navigation, and data sharing. This Android app is a part of the larger TAK family of products. [1]
Notch All-aspect missile defensive maneuver to place threat radar/missile on the beam (directly perpendicular). Modern pulse-doppler radars remove ground clutter by filtering out returns from stationary objects; putting the threat on the beam permits the defending aircraft to be confused with ground returns and hence disappear from the threat ...
