Abstract EN
For the purpose of target parameter estimation of the orthogonal frequency-division multiplexing (OFDM) radar, a high-resolution method of joint estimation on range and direction of arrival (DOA) based on OFDM array radar is proposed in this paper.
It begins with the design and analysis of an echo model of OFDM array radar.
Since there is no coupling between range and angle parameter estimation for a narrow-band signal, a method which exploits the data of one snapshot to estimate the range and angle of the target by means of multiple signal classification (MUSIC) based on virtual two-dimensional spatial smoothing in range and angle dimensions is devised.
The proposed method is capable of joint estimating the range and DOA of the target in a high resolution under a single snapshot circumstance.
Simulation experiments demonstrate the validity of the proposal.
