Low-peak pseudo-white-noise arrays

This letter presents a new approach to the construction of arrays having both a low peak-factor and a flat power spectrum. The proposed construction uses a systematic scheme and not any search methods. The size of the proposed array is 4n/sub 1//sup 2//spl times/2n/sub 2//sup 2/ for an arbitrary pair of positive integers n/sub 1/ and n/sub 2/. The proposed array can be used in applications such as position detection patterns, diffraction patterns for the calibration of laser beam, and so on.
