Abstract
A method of estimating the angular position θc of a target detected by a radar equipping a mobile carrier and emitting, via an steerable antenna, a signal, in the form of pulses, towards the target and receiving echoes from the reflection of said signal on the target, comprises: estimating, for each pulse or group of pulses of time index i, the angular position θ(i) of the antenna; estimating, for each pulse or group of pulses of time index i, the Doppler frequency fD(i) of the echo or echoes received; pairing, for each pulse or group of pulses of time index i, the angular position θ(i) and the Doppler frequency fD(i); and, estimating the angular position θc at least by solving the equationwhere λ is the wavelength of the radar, Va is the norm of the speed of the carrier and Vr,c is the radial speed of the target.
