Abstract

We have developed an approach of ISAR cross-range scaling. The fundamental principle is that we can estimate the rotating angle of target relative to radar-line-of-sight (RLOS) during the total coherent processing interval via the tomographic formation. However, the multi-dimensional search involved in the estimation of rotating angle will result in huge computational load. In this paper, an improved approach of cross-range scaling in ISAR is presented which takes the place of tomographic formation with the extended coherent processing and modifies the criterion to search the rotating angle. The processing results of computer simulated data and real data of model B-52 collected in a microwave anechoic chamber show that the improved approach is able to carry out the cross-range scaling of ISAR accurately. As compared with the previous method, its computational complexity is greatly reduced.
ISAR中一种改进的跨距离标度方法
我们开发了一种ISAR跨距离标度的方法。其基本原理是通过层析成像来估计目标在总相干处理时间内相对于雷达视距的旋转角度。然而,旋转角度估计中涉及的多维搜索会导致巨大的计算量。本文提出了一种改进的ISAR交叉距离标度方法,该方法用扩展相干处理代替层析成像,并修改了搜索旋转角度的判据。计算机模拟数据和B-52型微波消声室实际数据的处理结果表明,改进的方法能够准确地实现ISAR的跨距离标度。与之前的方法相比,该方法的计算复杂度大大降低。
