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 ...
This required the development of the klystron, the traveling wave tube, and solid state devices. Early pulse-dopplers were incompatible with other high power microwave amplification devices that are not coherent , but more sophisticated techniques were developed that record the phase of each transmitted pulse for comparison to returned echoes.
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 ...
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.
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 devices account for more than half of smartphone sales in most markets, including the US, while "only in Japan was Apple on top" (September–November 2013 numbers). [389] At the end of 2013, over 1.5 billion Android smartphones had been sold in the four years since 2010, [390] [391] making Android the most sold phone and tablet OS ...
In an interview with NBC News on Monday, Robin Radar Systems general manager Kristian Brost said the company’s radars can detect a drone in the sky, but “we can’t tell you who’s flying it ...
Since a DRFM system is designed to create a false target to a radar system, this technology can be employed to perform hardware-in-the-loop simulation. [1] [2] Hardware-in-the-loop simulation is an aid to the development of new radar systems, which allows for testing and evaluation of the radar system earlier in the design cycle. This type of ...
