Method for estimating the angular position of a target by radar detection and radar implementing the method

摘要

The method involves estimating an angular position of a steerable antenna (301) for each pulse or group of pulses of time index. Doppler frequency of echoes received from reflection of a radar signal on a target (301) is estimated for each pulse or group of pulses of time index. The angular position and the Doppler frequency are paired. An angular position of the target is estimated by solving a specific equation having parameters of wavelength (Va) of a radar, norm of the speed of a mobile carrier i.e. aircraft (300), and radial speed of the target. An independent claim is also included for a surveillance radar comprising a steerable antenna and an emission unit for emitting a radar signal in the form of pulses.
