面向目标容量的雷达通信一体化功率分配算法
Power allocation algorithm for target capacity in integrated radar and communication system
摘要
Abstract
In order to solve the problem of low power resource utilization in integrated radar and communication system,a power allocation algorithm for target capacity was proposed,which taked the total power of the system as the limit condition,and increased the number of targets satisfying the positioning accuracy while ensuring the communication channel capacity.Firstly,the Cramer-Rao lower bound of target positioning error was given,and exponential function was introduced to establish a power allocation model to maximize target capacity under power and channel capacity constraints.After adding the target weight factor,the problem of maximizing the target capacity was transformed into the problem of minimizing the total positioning error,and the alternate optimization algorithm was used to solve it.The simulation results show that the proposed algorithm can effectively increase the number of targets when the total power of the system is constant and the positioning performance and communication channel capacity are guaranteed.关键词
