Abstract :
Multicarrier phase-coded (MCPC) signals have been recently introduced to achieve high range resolution in radar systems. As in single carrier phase coded radars, the conventional method for compression of these signals is based on using matched filter or direct computation of the autocorrelation function. In the first part of this paper, we introduce a new method based on fast Fourier transform (FFT) that is mathematically equivalent to the matched filtering and has lower computational complexity compared to the traditional approach. Then based on this approach, another method is proposed that needs lower sampling rate to compress MCPC signals, which leads to the lower hardware and computational complexity requirements.
