Design of L-Band-Phased Array Radar System for Space Situational Awareness

Analysis of System Errors in Real-time Propagation of Signals in L – Band Phased Array Radar

NARL has active array radar which has been designed, developed and tested at 1280 MHz. This system comprises of planar microstrip patch antenna array fed by solid-state transreceiver (TR) modules, two-dimensional (2D) passive beam forming network (BFN) and direct IF digital receiver (DRx). Errors are the common factors that affect the data. The common errors are Random errors and Systemic error...

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 ...

Interferometric Imaging Radar for Space Situational Awareness Satellite Characterisation

The three-dimensional imaging of satellites from a groundbased radar is considered in a space situational awareness context. Utilizing the synthetic aperture radar (SAR) tomographic formulation and a model of the collection geometry in a specific low Earth orbit scenario, the shape and repeat nature of collection passes from ascending and descending orbits is evaluated and constraints on the fo...

Design and Application of Phased Array System

Since its invention, phased array has been extensively applied in both military and civil areas. The applications include target detecting and tracking, space probe communication, broadcasting, human-machine interfaces, and remote sensing. Although the phased array applications show a broad range of potential market, there are some limitations of phased array's development: high cost, complex s...
