<span lang="EN-US">Space borne synthetic aperture radar (SAR), an active microwave imaging sensor, comprising hundreds of transmit receive (TR) modules, is an important technique for earth observation in radar imaging payloads. The TR module is expected to have higher efficiency, light weight, lower loss and higher stability and reliability. Hundreds of modules are integrated onto the SAR based radar imaging payloads. Hence it is necessary that they are highly reliable for their mission life and repeatable during manufacturing and testing. The design and development of TR module starts with selection of right materials, processes and packaging techniques for miniaturization and improved thermal and radio frequency (RF) performance. The thermal and structural analyses coupled with experimental verification leads the way for production in larger numbers. The structural dynamic analysis revealed that the TR modules can withstand the dynamic loads during launch for the flawless operation. Results of the analyses are verified with actual testing. This paper describes the development cycle, need for repeatable production methods, innovative techniques for faster testing and characterizing of C band TR modules in larger numbers at multiple stages of their journey towards in-orbit performance. The C band TR modules realized are successfully integrated on to the Radar Imaging satellite and have shown excellent in-orbit performance.</span>

This paper discusses the architecture of an adaptive transmitting antenna array that allows highly flexible beamsteering. Antenna arrays are used in many digital signal processing applications due to their ability to locate signal sources. The Direction of Arrival (DOA) estimation is a key task of array signal processing, with the Taguchi method and Multiple Signal Classification (MUSIC). Although various algorithms have been developed for DOA estimation, their high complexity prevents their use in real-time applications. In this paper, we design and develop an implementation using Field Programmable Gate Array (FPGA Artix-7), which is the most widely used ARM processor in embedded systems. The antenna array is digitally controlled with the phases synthesized by the Taguchi method.
