Abstract

Costas arrays are permutation matrices that also provide a frequency indexing sequence that permits at most one coincident tone in cross-correlations of FSK waveforms. As such, they have obvious application as frequency indexing sequences in radar and communications when long codes with bounded autocorrelation are required or when Doppler is a significant portion of the transmitted bandwidth. All Costas arrays for orders less than 25 are known, with those for N=24 disclosed in the paper. Higher orders are found through number-theoretic generators and partial searches.

科斯塔斯阵列和雷达应用的组合协作

Costas阵列是排列矩阵，也提供频率索引序列，允许在FSK波形的互相关中最多有一个同音。因此，当需要具有有界自相关的长码或当多普勒占传输带宽的很大一部分时，它们在雷达和通信中作为频率索引序列具有明显的应用。小于25的订单的所有Costas数组都是已知的，而N=24的订单则在论文中披露。通过数论生成器和部分搜索找到更高阶。
