目前的跳频电台采用的捕获方案均在不同程度上受到了跳周期资源(简称跳资源)的约束。随着跳速的提高,跳资源相应的减少,采用原有的捕获方案将不能保证系统必要的抗干扰性能指标。为了解决因跳资源减少而引起的矛盾,论文提出了一种传输跳频图案的两级捕获方案。通过捕获方案的建立及捕获性能的分析,从计算结果可以看出:该方案从根本上避开了跳资源的约束,是一种适合中高速跳频的捕获方案。这个结论对于今后跳频电台的发展,具有重大意义。论文最后指出了该方案的不足。
The current acquisition schemes adopted by frequency hopping stations are all constrained to different extents by hopping resources. With the increase of the hopping speed, the hop resource is correspondingly reduced, and the original acquisition scheme can not guarantee the necessary anti-interference performance index of the system. In order to solve the contradiction caused by the decrease of hop resources, a two-level acquisition scheme for transmitting frequency-hopping patterns is proposed. Through the establishment of the acquisition scheme and the analysis of the acquisition performance, it can be seen from the calculation results that the scheme basically avoids the constraint of jumping resources and is a capture scheme suitable for medium-high-speed frequency hopping. This conclusion is of great significance to the future development of frequency hopping radio stations. Finally, the paper points out the shortcomings of the program.
