But unfortunately to analyze even a very simple array, I had to do cumbersome array factor evaluations to finding pattern nulls, gain, etc. I am not saying that those calculations were useless. As a matter of fact, those manual computations give us very interesting insight into concepts such ...
A planar phased array antenna assembly includes a first face sheet with a first plurality of radiating slots for a first frequency band and a second plurality of radiating slots for
Discusses some factors which a radar designer should consider in assessing which type of phased array system (if any) to employ, and outlines some fundamental antenna characteristics which may influence the radar design. The principal functions required from primary radar are general surveillance, ...

An optical dispersion technique for phased-array beam steering is proposed and analyzed. Optical true time delay using a high-dispersion compensation fiber (HDCF) and a phased array antenna (PAA) can provide a continuous radio-frequency squint-free beam scanning. When the dispersion of the fabrica...
Different types of antenna elements are used to make up an array. Those commonly used in phased arrays are the dipole and patch; refer toFigure 1. FIGURE 1.Common antenna types: (a) half wave dipole; (b) patch. The dipole is a basic half wavelength conductor fed at the center. A pat...
The S-STEP SAR payload adopted an active phased-array antenna based on a microstrip patch-array antenna, which is advantageous for miniaturization/lightweight, easy design/manufacturing, and brick-type TRM. Thus, a large space can be secured to install the SAR payload and body components on ...
The greatest difficulty in the design of phased array radars (PARs) used as sensors in a rocket tracking system (RTS) is the modeling step. It is a complex optimization problem due to the large number of possible solutions. In order to assist the design of PARs, the Genetic Algorithm with...
