Paper Abstract

We report on a wideband lidar-radar architecture in which range resolution is independent of pulse duration thanks to the use of a widely tunable intensity-modulated laser combined with a radar-like signal processing. We use a dual frequency laser which provides a modulated beam with a modulation frequency tunable over 1 GHz. A stepped-frequency waveform is obtained and 30 cm range resolution is demonstrated. Field experiments have been conducted on mobile targets, which assess the ability of this setup to measure simultaneously the range and the velocity. A velocity resolution of 1.70 m/s is demonstrated.
