Multichannel HRWS SAR Imaging Based on Range-Variant Channel Calibration and Multi-Doppler-Direction Restriction Ambiguity Suppression
TL;DR: The airborne real measured scan synthetic aperture radar data, which are acquired by a seven-channel in azimuth SAR imaging system with the system working at X-band, are utilized to demonstrate the performance of the newly proposed channel-calibration method and the new Doppler ambiguity suppression algorithm.
Journal ArticleDOI
Localization of Mixed Near-Field and Far-Field Sources Using Symmetric Double-Nested Arrays
TL;DR: A source localization scheme under the simultaneous existence of near-field and far-field sources using a symmetric double-nested array (SDNA) that significantly outperforms the existing methods for both DOA and range estimations.
Journal ArticleDOI
Frequency Diverse Array Beampattern Synthesis Using Symmetrical Logarithmic Frequency Offsets for Target Indication
Yi Liao,Wen-Qin Wang,Zhi Zheng +2 more
TL;DR: A new FDA framework is proposed, which adopts symmetrical and logarithmic frequency offsets together with multicarrier technique, to produce a dot-shaped beampattern for target indication and is verified by both numerical results and comparisons with existing FDA frameworks.
Journal ArticleDOI
Frequency Diverse Array Beampattern Synthesis With Taylor Windowed Frequency Offsets
TL;DR: Numerical results validate the superiority of proposed FDA in terms of mainlobe width, and sidelobe level, and the optimized parameters of the window function are determined.
Journal ArticleDOI
Transmit Beampattern Synthesis for Frequency Diverse Array With Particle Swarm Frequency Offset Optimization
Yi Liao,Jian Wang,Qing Huo Liu +2 more
TL;DR: In this article, a range-angle transmit beampattern synthesis method based on frequency offset optimization is proposed for frequency diverse array (FDA) elements, which provides a huge potential opportunity for target estimation and range-dependent clutter and interference suppression.
