QAM MAPPED OFDM SIGNAL PROCESSING ON RADAR APPLICATIONS
摘要
QAM mapped OFDM signal processing gives an opportunity to solve two of the main tasks of radar applications, i.e., target velocity and target range. Reviewing reflected signal constellation we can see the rotated and distorted mapping, which occurs as a result of the moving target. On the other hand when the mapping is only rotated around the zero, we have a reflected signal from a static target. After passing this signal through the frequency and target range filter banks we can easily get the Doppler frequency and time shift and consequently the velocity and the target range.
