30 April 1982 Relative Merit Of Coherent Vs Noncoherent Laser Radars
Author Affiliations +
The relative merits of coherent and noncoherent laser radars are reviewed. An information theoretic approach is used to investigate the tradeoffs between degrees of freedom (resolution) and signal-to-noise ratio in maximizing information in radar images. Similar tradeoffs between carrier-to-noise ratio and degrees of freedom are obtained for maximizing the signal-to-noise ratio in detection and estimation problems. It is shown that under some conditions noncoherent laser radars provide better performance than coherent radars, while under other conditions, the reverse is true.
