Evaluation of a Delay-Doppler Imaging Algorithm Based on the Wigner-Ville Distribution.

摘要

This report investigates the relative merits of a delay-Doppler imaging radar based on matched filter and Wigner-Ville approaches. Both approaches are formally equivalent; the relative merits of each method are based solely on implementation issues. Given the current state of optical delay-Doppler radar and signal processing capabilities, the matched filter approach provides significant advantages over a Wigner-Ville-based approach. Additional applications of the Wigner-Ville distribution to laser radar measurements are discussed. (KT)
