In this paper a novel approach for the calculation of the radar range profile in OFDM radar systems is presented. The proposed algorithm operates directly on the modulation symbols and overcomes the typical drawbacks of correlation based baseband signal processing. An example system configuration as well as simulation results from a dedicated MatLab model will be presented and discussed.I.
The time domain radiation properties of UWB antennas are analyzed, especially the angular dependent impulse distortion, with respect to the signal transmitted in the main beam direction, is investigated. The correlation properties of the radiated pulses are determined by the so called fidelity . The fidelity is together with the peak pulse amplitude a powerful tool for the characterization of impulse radiating antennas. The results are applied to two different UWB antennas, a Vivaldi antenna and a Bow-tie antenna. The spatial regions with good correlation and high peak power are determined for both by measurements for verification. The results are vital for UWB impulse communications, and for UWB Radar as well.
