The system level issues that any Doppler ladar, operating from a polar orbiting platform, will confront are described. Emphasis is given to signal-to-background issues. It is found that the ladar behavior is quite distinctive depending on the relationship between viewing direction and satellite motion. The relativistic correction to the Doppler shift is analyzed and compared to the signal. The results indicate the need for taking account of the relativistic effect.
