Adaptive 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 کاملSystem 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 کاملPhased array antenna using MEMS phase shifter
This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...
متن کاملMultifunction Phased Array Radar Resource Management: Real-Time Scheduling Algorithm
In this paper a real-time task model of multifunction phased array radars is built, and a novel scheduling algorithm is proposed. This algorithm takes the priority of task’s function mode and deadline into account synthetically, and can adapt well to different load conditions. Based on the task model, the algorithm can achieve the variety of scheduler’s time load in a real-time fashion and adju...
