Performance verification of symbol-based OFDM radar processing

In this paper a recently proposed novel processing approach for OFDM radar is verified with measurements. This processing algorithm directly calculates a radar image from the transmitted and received modulation symbols that compose the OFDM signal without the need for performing correlation operations. The implementation of a suitable system setup is described. The measurement results confirm that with this approach a very high dynamic range can be obtained. Moreover, the SNR in the measured radar images is investigated. The results prove that the proposed algorithm provides high processing gain.
