Abstract | ||||
Cymbeline Radar is an old British mortar locating radar operating in x band using a Foster scanner. It has a nominal 100 kW peak output power using an old magneton, and a nominal pulse repetition frequency of 4000 pulses/second with 0.25 microsecond pulse width. It was built based on analog technology. This radar suffers from ageing, instability, in-coherency, poor accuracy, and difficult maintenance. In the present work, a proposed modified version of this radar is introduced. The proposed version depends on changing the radar parameters such as peak power, pulse width, and waveform generation and processing based on advanced technologies. A 6 KW Traveling Wave Tube (TWT) is suggested with a transmitted waveform of 6 microsecond pulse width and Barker code modulation. The same pulse repetition frequency is used. These parameters are chosen to achieve the designed radar specifications with an enhanced performance, and available technology The waveform generation and signal processing is achieved using Field Programmable Gate Arrays(FPGA’s) which are best suited for signal processing applications that requires real time processing. The proposed signal processor includes matched filter and pulse compression with side lobes cancellation, Moving Target Indicator (MTI), Doppler processing, and Constant False Alarm Rate (CFAR) processing. | ||||
