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 ...
متن کاملAdaptive Array Processing for Multi-mission Phased Array Radar
As the use of phased array radars becomes more established for weather surveillance, adaptive array processing techniques will become more important to the weather radar community. Such techniques can be applied to phased array radars to improve angular resolution and also to suppress clutter compared to conventional beamforming methods. Thus, enhanced details of weather phenomena can be realiz...
متن کاملBayesian 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...
متن کاملPhotonic Integrated Circuits for Phased-array Beamforming
Photonic integration is very promising to bring down volume and weight of phased-array beamforming networks. In addition, photonics allows for increased functionality for widebandwidth systems. In this paper we demonstrate the feasibility of phase and amplitude control of a 16-element phased-array antenna with a single InP integrated circuit. The concept and design of an optical phase locked lo...
متن کاملAdaptive VLSI Architecture of Beam Former for Active Phased Array Radar
This paper describes architecture for a digital beam former developed for 16 element phased array radar. The digital beam former architecture includes the complex operations such as down conversion which is done in parallel for the signal coming from each of the antenna elements and the filtering. A high performance FPGA is employed to perform these operations. An echo signal of 5 MHz riding on...
