where , is the amplitude of the electric field scattered by the mth scatterer, is the position of the mth scatterer, is the carrier frequency and , represents the shift in phase of the scattered wave in the direction of the radar due to the relative radial velocity of the target with respect to the radar, while , and are respectively the phase ...
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
Radar geo-warping is the adjustment of geo-referenced radar images and video data to be consistent with a geographical projection.This image warping avoids any restrictions when displaying it together with video from multiple radar sources or with other geographical data including scanned maps and satellite images which may be provided in a particular projection.
ARINC 708 uses a data transfer method using transformer-coupled Manchester encoded signal, like the MIL-STD-1553 protocol. Termination of the bus is essential for good signal quality.
