Abstract :
This letter proposes a new ultra high frequency (UHF) radar system called UHF surface dynamics parameters radar (USDPR). The hardware has been developed based on the surface currents radar (SCR) system for an all-digital receiver platform, which realizes direct radio frequency (RF) band-pass sampling and orthogonal demodulation of the amplified echo, as compared with traditional intermediate frequency (IF) receivers. Closed-loop test and field test proves the correctness of the design.
