Abstract
A distance and speed estimation algorithm for OFDM based radar is analysed statistically. The maximum likelihood estimator is derived and compared to previous results. A connection to spectral analysis is drawn, simplifying the analysis of the estimator in question. Finally, a method to evaluate the performance of the algorithm is presented and conclusions for the structure of the OFDM signals are drawn. It is shown that the estimation algorithm works well above an SNR threshold, but rapidly degrades below.
