从新的视角来看待干涉仪的测向与定位应用

Analysis of Direction Finding and Passive Location Based on Interferometer

传统的多基线干涉仪测向理论与基于干涉仪相位差变化率的定位理论,在当前电子侦察设备研制中获得了广泛应用,但干涉仪本身的吸引力还不仅局限于此。从新的视角出发,重新审视了干涉仪的测向与定位这两类典型应用:利用高精度时差测量思想,引出了单基线干涉仪无模糊测向理论;利用干涉仪相位差变化率与测向角变化率的等价性,引出了运动单站定位与多站测向交叉定位的统一理论模型。上述这些对干涉仪测向与定位的新理解,展现了电子侦察中干涉仪的无尽魅力所在,为干涉仪更广泛的应用提供了新的思路。

The traditional multi-baseline interferometer direction measure theory and passive lo-cation based on the phase-difference changing-rate of the interferometer are widely utilized in e-lectronic reconnaissance. But their interests are not only limited in these areas. Two typical ap-plications of the interferometer looked upon from a new angle of view. The theory about the di-rection finding using single baseline interferometer without ambiguity is deduced from the time difference accurate measure. The uniform theory model about single moving observer location and multiple observers bearing intercrossing location is brought forward from the equivalence be-tween the phase difference changing rate of the interferometer and the direction angle changing rate. The above novel ideas provide strong attraction of the interferometer in electronic recon-naissance and also bring the new route for the wider application of the interferometer.
