A Wideband Noise Radar System Using a Phased Array with True Time Delay

Noise radar has become attractive owing to progress in hardware technology. Aside from the low probability of exploitation, use noise waveform is likely grow due its interference features, especially circumstances where multiple radars operate same band. In this study, we developed and tested a wideband for ground-moving vehicle. It operates X-band with an instantaneous bandwidth 1.5 GHz. The true time delay (TTD) was applied correct distortion beam pattern by wide bandwidth, correlators were implemented high-speed parallel processing using field programmable gate array (FPGA). outdoor experimental results presented.
