Radar signals are synthesized having a region of zero autocorrelation sidelobes with a relative width of 1/3\leq \varepsilon < 1 in the vicinity of the central peak of an aperiodic autocorrelation function. These signals represent a train of two binary phase-coded pulses encoded by pair of complementary sequences of length N=2k , with an integer k\geq 2. The correlation characteristics of the synthesized signal are analyzed. A compression algorithm for these signals, multichannel with respect to the Doppler frequency, is considered. It includes a combined algorithm for fast Walsh and Fourier transforms.
