Design and Measurement of Active Phased Array Radar Digital Receiver

A GPS Digital Phased Array Antenna and Receiver

NAVSYS High Gain Advanced GPS Receiver (HAGR) uses a digital beam-steering antenna array to enable up to eight GPS satellites to be tracked, each with up to 10 dBi of additional antenna gain over a conventional receiver solution. This digital, PC-based architecture provides a cost-effective solution for commercial applications where more precise GPS measurements are needed. The additional gain ...

The next Generation Fully Digital and Scalable Active Phased Array Radar System at Sea

Bayesian Analysis of Linear Phased-array Radar

A number of methods have been developed to analyze the response of the linear phased array radar. These perform remarkably well when the number of sources is known, but in cases where a determination of this number is required, problems are often encountered. These problems can be resolved by a Bayesian approach. Here, a linear phased-array consisting of equally spaced elements is considered. A...

System Requirements for Phased Array Weather Radar

Preamble This is the final report to Lockheed Martin on the requirements for a phased array weather radar. Discussed herein are those meteorological requirements that need to be met by weather radars having either reflector type antennas or active phased array elements. These requirements impact the design of the antenna, the transmitter-receiver, and signal processor. Justifications for these ...

Optically Controlled Phased Array Radar Receiver Using SLM Switched Real Time Delays

We report the results of a demonstration of a real time delay, optically controlled phased array radar receiver. This implementation employed a free space configuration based upon an optical switching network using liquid crystal spatial light modulators (SLM’s). A three-delay unit, two-antenna array receiver was implemented at an optical wavelength of 1.3 pm and demonstrated “squint-free” oper...
