针对跳频电台多台同址时相互间同址干扰严重和采用分频段跳频方式导致跳频增益小的不足,从子网内、子网间和跳频同步信号无干扰3个层次分析跳频异步组网中的全频段宽间隔频率分配约束条件,并建立代价函数;根据约束条件的特点对模拟退火算法的实际应用进行改进,提出同址干扰限制下的全频段宽间隔跳频异步组网频率分配方法.计算机求解结果表明新方法可以很好地解决同址干扰限制下的跳频频率分配问题,提高跳频通信抗干扰性能,对跳频电台发挥性能优势具有重要意义.

The cosite interference is aggravated when several frequency-hopping (FH) radios are located on the same platform,and the small hop-set used in this condition results in low FH gain.The constraints in the in asynchronous FH networks with cosite restriction include constraints within subnets,constraints among subnets and no interference of the synchronization constraints,and cost function is based on the above analysis.The application of the simulated annealing (SA) algorithm was improved by the characteristic of the violations of the constraints.The method of frequency assignment problems (FAPs) in the asynchronous FH networks with cosite constraints was presented and the computing results indicate this method can realize the FH communications in the full-band with given minimum gap.This approach gave a method to actualize the advantages of FH communications.
