Abstract :
An airship-mounted synthetic aperture radar system for surveillance of minefields or foliage-covered targets is presented. The system consists of airship platform, light-weight low-frequency ultra-wideband radar with real-time processing capability, ground station and GPS/INS sensors. Stepped-frequency gated-wave signal is adopted to achieve short range operation and ultra-wideband signal generation. Modified back-projection imaging algorithm is used to compensating intra-pulse Doppler Effect and motion errors. The experimental results show the effectiveness of the system for minefield surveillance.
