It contains a 16×16-element antenna array. There are 16 TR-Modules. Each TR-Module feeds 16-elements in the array. Tapering is required to suppress the side lobe level to approximately 17dB. The 16-outputs from each TR-Module should not be of equal amplitude and they should be weighted according to the amplitude distribution.
The main aim of this project work is to design and simulation of
1. (a) Feeder network which consists of Unequal Amplitude Equal-Phase Splitter and unequal amplitude quadrature hybrid coupler.
(b) Beam forming network components which consists of 3dB 90 degrees Hybrid couplers,Cross overs and phase shifters.
2. Micro strip patch antenna as a single element and 1X16 Element linear array in the 16x16 planar array for 430MHz Troposphere wind profiling radar.
The design and simulations are to be carried out using IE3D and ANSOFT DESIGNER simulation softwares.M.

Development and Testing of Low Pass Filters for Filter Section Unit. (Frequency Range-30-500MHz).Project 2 : ST-RADAR[206.5MHz]Role : Development and Testing.Company : Electronics Corporation of India Limited, Hyderabad.Description :
In the active aperture phased array system each antenna of the array is connected to a Transmit receive module popularly called TR module (TRM). These basic building blocks of the TRM are transmitter, duplexer, phase shifter, LNA. A Co-axial cable, forming the feeder network, is typically used for connecting the TRM to the antenna. Since the transmitter and LNA are very close to the antenna, transmit and receive losses are typically less than 0.5 dB. The entire array consists of as many number of TR modules as antennae. Any failure of few of the TR modules does not significantly affect the performance of the radar.
