1. A system for heating surfaces within a remote SODAR apparatus, the system comprising:

  • a transducer array comprising a plurality of acoustic transducers;

    a sound mirror comprising a rear surface and a sound-reflective surface, wherein the sound-reflective surface is disposed opposite the transducer array and on an opposite side of the sound mirror as the rear surface;

    a drain path leading out of the remote SODAR apparatus;

    a heater;

    a closed loop system coupled with the rear surface of the sound mirror and coupled with the heater, the closed loop system comprising channels and a liquid disposed within the channels, the closed loop system arranged to circulate heated liquid within the channels from the heater to the rear surface of the sound mirror and proximate the drain path;

    one or more conductive structures thermally coupled with the closed loop system and the rear surface of the sound mirror;

    sensors that sense precipitation and temperature; and

    a controller coupled with the sensors and the heater, the controller configured to cause the heater to heat the liquid in the closed loop system in response to either or both sensed precipitation and sensed temperature from the sensors.
