摘要:

多基线相位干涉仪接收机是电子侦察中非常重要的一种传感器资源,其主要优点是测角精度高、处理速度快,在射频测向应用较为广泛。结合相位干涉仪测向的工作原理,提出了基于多信号交叠干扰的策略,研究了多信号对干涉仪测向的干扰机理,并通过建模仿真对上述干扰策略进行了评估。仿真结果表明:交叠的多信号对相位干涉仪测向的干扰十分明显,使其无法获得射频目标的真实方位,并输出同时到达信号的错误指示。

Abstract:

Multi-baseline interferometer (MBI) receiver is a kind of important sensor for electronic reconnaissance, which is widely used in radio direction finding (RDF) with the advantages of high accuracy of angle measurement and fast processing speed. A jamming strategy of multiple overlapping signals is proposed according to the working principle of the interferometer direction finding, and the jamming mechanism of multiple signals on interferometer direction finding is studied. Modeling and simulation are carried out to evaluate the jamming strategy. The simulation results show that the multiple overlapping signals can significantly jam the interferometer direction finding and make the interferometer fail to obtain the true direction of the radio frequency (RF) target and output the wrong indication of simultaneous arrival signals at the same time.

Key words: radio direction finding, multi-baseline interferometer, simultaneous arrival signals, multiple overlapping signal jamming, angle of arrival error
