New Results Using Polyomino-Tiled Subarrays for Time-Delay Control of Wideband Arrays

Abstract

This paper presents recent results describing the use of polyomino subarrays to introduce time delays into phased-array systems. Results for arrays of 8-element subarrays show suppression of peak quantization lobes to levels below -14 dB, relative to the quantization lobes of 8-element rectangular subarrays. Since algorithms for producing arbitrarily large arrays that tile rectangular areas are not available, we have combined smaller arrays chosen to be statistically independent. These have allowed the evaluation of ensemble averages of array gain, average and peak sidelobe levels.
