摘要
为满足多路GNSS欺骗干扰信号整体获得目标接收机高捕获性能的实际应用需求,设计了一种多路信号互相关干扰约束下的信号功率最优控制策略。分析了多路欺骗信号功率对噪声基底的影响,研究了在此情况下欺骗信号的捕获性能。以噪声基底上升和欺骗信号相对捕获概率为约束,构建了控制策略的目标函数,利用遗传算法进行寻优计算。仿真结果表明,该策略实现了多路欺骗信号的捕获性能优于真实信号,且此时噪声基底的抬升不超过10 dBW,欺骗信号功率不具有相关性。
In order to meet the needs of the high captured performances integrally by target receiver for multiple GNSS spoofing signals, a power control strategy based on the cross-correlation interference of multiple signals is proposed. This paper analyzes the influence of multiple spoofing power on the noise floor, and discusses the acquisition of spoofing signal. Taking the rise of noise floor and spoofing relative acquisition probabilities as a bound, an objective function is built, and the optimized solutions is obtained based on genetic algorithm. The simulations show that the performance of multiple spoofing acquisition is superior to that of the authentic according to the proposed strategy, and at the same time the noise floor rises no more than 10 dBW, and the spoofing power is uncorrelated.
