Studies on cloud microphysics, cloud intra structure on vertical/3D scale, its evolution in time and space in real time has not been carried out much in India due to non availability of indigenous ka-band cloud prifiling radar system. The high cost & maintenance of the imported system has prohibited Indian scientists to procure such radars in numbers. Persistant requirement put forward by Indian...
A low power zenith looking Ka Band dual polarization Cloud Radar is designed and fabricated by Society for Applied Microwave Electronics Engineering and research (SAMEER) to study the clouds during monsoon. This radar is installed on the terrace of the SAMEER building and conducted test operations in single polarisation mode during monsoon period(June to September, 2013–2015). The system is observed...
With the recent trends in wireless communication technology, the inherent problems associated with the past radio receivers are now being exterminated by the use of its digital counterparts. In the past radio receivers were designed with analog circuitry. This inherently has the same problems that all analog circuits have, overcoming this disadvantages the Two Channel Digital receiver is used for...
The paper discusses the application of VLSI technology to implement the functions of TSG of a radar system using VHDL with behavioral model, as the HDL and targeting it to a FPGA. The TSG is the heart of radar application to generate timing and control signals to operate radar in different phases like detection, tracking and acquisition, and hold mode. The advantage of TSG design with FPGA is that...
Radar operating in High pulse repetition frequency (HPRF) suffers eclipsing loss because of high duty cycle. Multi PRF systems are able to reduce eclipsing loss but proper selections of PRF's are necessary to minimize Eclipsing loss as low as possible with the given specification (duty cycle, range, maximum relative velocity of target, etc). Proposed algorithm for selection of multi-HPRF's try to...
