Spectral Estimation-Based OFDM Radar Algorithms for IEEE 802.11a Signals

Recently, OFDM radar has gained attention as new algorithms for range and Doppler estimation specific to OFDM signals have been developed. The major advantage of OFDM is that it is both well-suited for radar processing as well as being suitable for communication. In previous work, we have proposed parametrizations for OFDM signals which suit the radar problem well. However, the proposed algorithms are independent of the OFDM signal parametrization, and it is therefore interesting to see how well they work with other, more commonly available signals. For this paper, we examine a common type of signal-OFDM signals according to the IEEE 802.11a standard-and determine how they could be used in a radar application.
