Figure 1. Normalised array factor of a 32-element linear array at two different d/λ spacings. Analogy to Sampled Systems An analogy to visualise grating lobes is to think of aliasing in a sampled ...

Phased array antenna systems are at the cusp of ubiquity. We now see Multiple-Input Multiple-Output (MIMO) antenna systems on WiFi routers. Soon phased array weather radar systems will help to pred… ...

Until recently phased array radar has been very expensive, used only for military applications where the cost of survival weighs in the balance. With the advent of low-cost microwave devices and un… ...

A phased array system shows analogous A-scan waveforms for reference, but in most instances the waveforms will be complemented by B-scans, C-scans, or S-scans as shown in the figures below. With the ...

This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems. It examines the new capabilities recently added to the NI AWR Design ...

Phased-array systems have many advantages over single antennas. One advantage of having multiple transmit and receive elements is that you can apply complex weighting to each element to form a beam.

Phased array radars also have the ability for the user (i.e., National Weather Service) to direct the radar beam where they want it to go. This, too, translates to faster scan time during severe ...

Phased-array radars are not without disadvantages. Most are functional through a cone of just 120 degrees, because the width of the main beam diminishes the farther it gets from broadside.

Micromachining can be used to create a infra-red beam-forming phased array, according to engineers at University of California, Berkeley, who have made a 160 x 160 array on a 3.1 x 3.2mm die that can ...
