It has important significance on the investigation of ground-based detection of mars aerosol for study mars atmospheric environment. To perform aerosol detection based on the constraint of saving mars rover's or lander' s volume and weight, we investigated the feasibility of designing a Mie-Lidar which compacted with rover based Laser Induced Breakdown Spectroscopy (LIES). Beam splitter parts and detection module, along with rover based LIBS' s hardware, comprised the LIES based Mie-Lidar, the LIBS and the Mie-Lidar work independently and they didn't interfere each other. One day's primitive data collected by Phoenix mission's lander was processed, and extinction coefficient profile was derived, with this profile and LIPS' s parameter, signal-to-noise ratio (SNR) of the Lidar calculated. The result showed that LIBS based Lidar reached SNR of 25 dB at 4 km height, i.e., top of martian boundary layer, and downgraded to 0 dB around 10 km altitude. Such outcome proved that letting LIBS based Mie-Lidar working on mars is feasible. It is not only volume and wight saving, but simplifies data recovering processess when we detect mars aerosol with LIBS based Mie-Lidar.
