Abstract:
Using QAM mapped OFDM signal in radar applications it is possible to get from the signal constellations both the target velocity and target distance from the radar station. When in the reflected signal constellation we get the rotated and distorted mapping that is mean that the signal is reflected from the moving target, while on the other hand, when the mapping is only rotated around the zero, we have a reflected signal from static target. Getting that signals and passing them through frequency and target distance filter banks we get the Doppler frequency and time shift and, consequently, the velocity and the distance of the target.
