摘要
量子雷达基于量子态特性对目标探测识别,可有效克服复杂电磁环境和目标隐身特性影响。针对光量子在大气中传播时易受介质吸收和散射影响的问题,提出利用分光链路模拟大气介质的方法,对目标量子雷达散射截面进行了研究。通过引入单光子波动方程,采用分光链路模拟大气介质,得到衰减条件下光子波函数,推导衰减条件下量子雷达散射截面公式,并对衰减条件下单曲面量子雷达散射截面进行仿真。仿真证明,在不同入射角条件下,量子雷达散射截面主瓣峰值随衰减系数增加而减小,入射角对量子雷达散射截面无影响;在0℃、能见度30 m条件下,目标量子雷达散射截面主瓣峰值随波长增加。
Quantum radar can effectively overcome the effects of complex electromagnetic environment and target stealth characteristics based on the characteristics of quantum states to the detection and the recognition of targets.Aimed at the problem that the light quantum is susceptible to medium absorption and scattering while propagating in the atmosphere,a method of simulating atmospheric media using a spectroscopic link is proposed.The scattering cross section of the target quantum radar is studied.By introducing the single photon wave equation and using the optical splitting link to simulate the atmospheric medium,the photon wave function under the attenuation condition is obtained,and the quantum radar scattering cross section formula is deduced under the attenuation condition,and the single-curved quantum radar cross section under the attenuation condition is simulated.The simulation results show that the peak value of the main lobe of the quantum radar scattering section decreases with the increase of the attenuation coefficient at different incident angles,and the incident angle has no effect on the quantum radar cross section;The peak of the petal for the target quantum radar cross section increases with the wavelength when the temperature is at 0 ℃ and the visibility is 30 meters.
