频率分集阵列对干涉仪的角度欺骗效果
|
摘要
针对干涉仪的测向隐蔽性问题,提出了一种基于频率分集阵列(FDA)对干涉仪的角度欺骗方法。干涉仪通过求取各天线接收到信号的相位差确定信号到达角,而FDA由于各阵元具有微小频偏造成其相位差并不满足求解关系,从而实现角度欺骗。首先,利用模型建立法和欧拉公式法2种方法建立了FDA波束相位模型;然后,从建立的2种模型出发,论证了FDA发出信号对干涉仪具有角度欺骗效果;最后,仿真分析了干扰距离、阵元间距、发射频率、频率增量等因素的影响。理论分析与仿真结果表明,FDA对处于远场的干涉仪目标有良好的欺骗效果。
A method of angle deception jamming for interferometer based on frequency diversity array( FDA) is proposed to solve the problem of direction-finding concealment of interferometer. The interferometer determines the angle of arrival by obtaining the phase difference of the signals received by each antenna,and the phase difference does not satisfy the solution relation due to the frequency offset of each element of FDA,so that the angle deception is achieved. This paper proposes two algorithms( FDA model establishment and Euler formula) to establish the FDA signal phase distribution model. It is proved that FDA signal has an angle deception effect on interferometer. Based on the principle of interferometer,the influence of interference distance,interval of array element,emission frequency,frequency offset,etc. is analyzed. The theoretical analysis and simulation results show that FDA has a good deception effect on the interferometer in far field.
