摘要

波前调制电磁波在雷达成像领域，特别是前视成像领域有着重要的应用。为了获得良好的方位角分辨率和高信噪比，期望调制场同时具有与空间相关的相位前和收敛强度分布。本文介绍了一种新的波前调制方法及其在目标成像中的应用。首先，提出了基于傅里叶合成的波前调制场生成方法，设计了波前相位随横距角线性变化且能量收敛的辐射场；随后，提出了基于该波前调制场的成像方法。结果表明，该成像方案具有较强的抗噪声能力。

Object Imaging Method With Electromagnetic Wavefront Modulation in Forward-Looking Sight

The wavefront modulated electromagnetic (EM) wave has important applications in radar imaging realms, especially for forward-looking sight. To achieve good azimuth resolution and high signal-to-noise ratio (SNR), the modulated field is expected to have space-dependent phase front and converged intensity distributions simultaneously. In this letter, a novel wavefront modulation method and its application for object imaging are developed. First, the generation method of wavefront modulated field based on Fourier synthesis is proposed to design the radiation field, where the wavefront phase changes linearly as a function of the cross-range angle and the energy is converged. Subsequently, the imaging method based on this wavefront modulated field is proposed. Results indicate the effectiveness of the imaging scheme, which is robust against the noise influence.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
