Abstract :
By exploring the orthogonal frequency-division multiplexing (OFDM) signal structure to build a frequency model, a generalized likelihood ratio test is presented, together with simulations of probabilities of detection of an OFDM based passive radar. The new analytical model gives insight into system components inter-dependence. It allows both the analyzis of Doppler shift rotation approximation and the study of its effect on detection performance.
