RADAR signal processing for target range, Doppler and DoA estimation
Nauman Anwar Baig, Aamir Hussain · 2017
Radar target detection is a two dimensional search problem. The radar signal processor has to simultaneously estimate target's range and velocity by processing the received echo signal. Direction of Arrival (DoA) of the target is an other parameter to be estimated for which Linear and Planar arrays are being used and processing is done in a separate processor. In this paper, a radar signal processing algorithm is presented for the estimation of target parameters (range & Doppler shift). The RSP algorithm is demonstrated through computer simulation. Target's direction of arrival estimation (DoA) is discussed. A comparison of different DoA estimation algorithms is presented based on their computational complexities and performance. The presented Radar signal processing algorithm and the comparison of DoA algorithms may be useful for radar and antenna system designers in realizing the physical systems.
