| 中文摘要 | aperture patterns play a vital role in coded aperture imaging ( cai) applications. in recent years, many approaches were presented to design optimum or near-optimum aperture patterns. uniformly redundant arrays (uras) are, undoubtedly, the most successful for constant sidelobe of their periodic autocorrelation function. unfortunately, the existing methods can only be used to design uras with a limited number of array sizes and fixed autocorrelation sidelobe-to-peak ratios. in this paper, we present a novel method to design more flexible uras. our approach is based on a searching program driven by direct, a global optimization algorithm. we transform the design question to a mathematical model, based on the direct algorithm, which is advantageous for computer implementation. by changing determinative conditions, we obtain two kinds of types of uras, including the filled uras which can be constructed by existing methods and the sparse uras which have never been mentioned by other authors as far as we know. finally, we carry out an experiment to demonstrate the imaging performance of the sparse uras. |
