Attributes of the ubiquitous phased array radar

This paper reviews the concept and properties of a ubiquitous radar, one that looks everywhere all the time. The receiving antenna of a ubiquitous radar consists of contiguous directive beams covering the same region as the wide beam (quasi-isotropic) transmitting antenna. Such a radar has the important advantage of performing multiple radar functions simultaneously without the serious limitations of a conventional phased array radar that has to perform its multiples functions sequentially, one at a time. Briefly described are the general characteristics of such a radar, its advantages, and several of its potential applications. The digital beam-forming ubiquitous radar is a method for achieving significant radar capabilities not readily available with conventional radar architectures.
