On the Single-Target Accuracy of OFDM Radar Algorithms
Two OFDM radar algorithms (the Maximum Likelihood and a MUSIC-based algorithm) are introduced and their fundamental limits concerning accuracy are explained. To simplify the analysis, the authors research the special case of only one target in the radar's detection range, which facilitates the individual effects on the estimation quality. Through simulations, they can show that OFDM radar works well for this case. OFDM signals have become an interesting choice for radar. They allow for separate estimation of target distance and Doppler shift by means of spectral estimation algorithms and can be used to transmit information at the same time.
