Abstract
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.
