Sinclair 산란 행렬은 고정된 레이더 범위에서 정의됩니다. 레이더 표적이 범위 방향으로 확장되면 반사된 신호 또는 복합 산란 매트릭스가 다중 반사의 상호 작용을 겪게 됩니다. 산란행렬은 모양, 크기, 방향, 재질 등의 표적변수와 주파수, 편광, 입사각 등의 레이더 변수의 영향을 받기 때문에 일반적인 표적의 대표적인 산란행렬을 특정하기는 어렵습니다. 따라서 우리는 가장 간단한 표적, 와이어 및 산란 행렬을 선택하여 복합 산란 행렬에 대해 범위 방향으로 정렬된 표적의 효과를 조사합니다. 먼저, 간격으로 인한 위상차를 갖는 와이어의 복합 산란 행렬에 대한 간단한 공식을 제시합니다. 그런 다음 FDTD 방법을 사용하여 범위 방향의 간격을 변경하면서 산란 현상을 조사했습니다. FDTD 결과는 두 개의 와이어가 구(플레이트) 및 2면체 코너 반사기(이평면) 구성요소 생성기가 될 수 있음을 보여줍니다. 그리고 4개의 와이어가 좋은 나선 구성 요소 생성기가 될 수 있습니다. 이러한 현상은 실험실 측정을 통해 검증됩니다. 그 결과, 대상 분해는 범위 측면에서 신중하게 수행되어야 한다. 레이더의 거리 분해능이 충분히 높지 않으면 원하는 표적의 산란 매트릭스가 뒤에 있는 표적의 영향을 받을 수 있습니다.

Abstract: The Sinclair scattering matrix is defined in a fixed radar range. If a radar target extends in the range direction, the reflected signal or the compound scattering matrix will undergo interaction of multiple reflections. Since scattering matrix is subject to target parameters such as shape, size, orientation, material, and radar parameters as frequency, polarization, and incidence angle, it is difficult to specify a representative scattering matrix of a general target. Therefore we choose the simplest target, wire, and its scattering matrix to examine the effect of targets aligned in the range direction with respect to the compound scattering matrix. First, we present a simple formula for the compound scattering matrix of wires with the phase difference due to spacing. Then, we employed the FDTD method to examine the scattering phenomena, changing the spacing in the range direction. The FDTD result reveals that two wires can become sphere (plate) and dihedral corner reflector (diplane) component generators; and that four wires can become a good helix component generator. These phenomena are verified with a laboratory measurement. From the result, the target decomposition should be carefully carried out in terms of range. If a range resolution of a radar is not high enough, the scattering matrix of the desired target may be affected by the targets behind.
