Constant modulus sequence set design with low weighted integrated sidelobe level in spectrally crowded environments

Dear editor, Radar waveform design with desired correlation properties has received considerable attention because of its perfor-mance improvement in the detection of a weak target[1,2].Moreover,owing to the increasing demand for access a wide radio frequency spectrum,coexistence among radar and telecommunication systems are currently instrumental in solving the spectrum-congestion problem[2].
