radar antennas: Topics by WorldWideScience.org Topics covered include array signal processing, array calibration, adaptive digital beamforming, adaptive monopulse, superresolution, pulse compression, sequential detection, target detection with long pulse series, space-time adaptive … phased array feed: Topics by WorldWideScience.org For the traveling wave feed of a planar slot array, one has to design the tilt angle and length of each coupling slot such that the amplitude and phase of excitation of each radiating waveguide are close to the desired values.
Waveguide slot array antennas have been excellent candidates for commercial and military applications in millimeter- wave frequency bands due to their advantages ofAlternating-phase-fed waveguide slot arrays were then proposed to implement broadband resonant characteristics [9, 10].
Description: Broadband directional antenna, ideal for use in EMC measurements The Double-Ridged Waveguide Horn Antenna R&S®HF907 with linear polarization is a compact broadband transmitting and receiving antenna for the frequency range of 0.8 GHz to 18 GHz. Due to specific calibration Form Factor: External; Polarization Type: Linear Array Antenna for Synthetic Aperture Radar Operating in X ... including RadarSAT-1, X-SAR, and ERS-1/2 have adopted waveguide slot array antennas because of their inherent advantages of high efficiency, mechanical strength, high power handling capability, and ease of fabrication. Conventional waveguide slot array antennas unfortunately have a limited bandwidth. To overcome this deficiency 梁仙灵 | 电子工程系副教授 - 上海交通大学 现代天线研究中心 ... Meiqing Qi, Xianling Liang, Broadband ridged waveguide slot antenna array fed by back-to-back ridged waveguide ... , Hong-tao Zhang, Broadband antenna array for um ... A broadband slotted ridge waveguide antenna array - INFONA A longitudinally-slotted ridge waveguide antenna array with a compact transverse dimension is presented. To broaden the bandwidth of the array, it is separated into two subarrays fed by a novel compact convex waveguide divider. A 16-element uniform linear array at X-band was fabricated and measured to verify the validity of the design.
