Microwave Microscope

Metadata Updated: March 8, 2017

FUNCTION: Makes ultra-high-resolution field measurements. The Microwave Microscope (MWM) has been used in support of several NRL experimental programs involving sea scatter and mine detection.DESCRIPTION: The MWM, an ultra-wideband, ultrahigh-resolution, dual-polarized measurement radar system, has been designed, implemented, and used in the field to measure ocean surface scattering at X-band frequencies. This experimental system uses a video-excited traveling wave tube (TWT) to produce 2-kW peak power transmit pulses as short as 150 ps in duration. Instantaneous receive bandwidths greater than 8 GHz are supported by a unique direct sampling detector that uses off-the-shelf digital sampling oscilloscope components. Data output consists of coherent I and Q measurements in a fixed number of range cells at re-sample periods as short as 25 [HTML_REMOVED]s. Final system range resolution is better than 2 cm. The system has been used at a field site at the Atlantic Undersea Test and Evaluation Center (AUTEC), in the Bahamas, to measure ocean surface scatter under high wind and rough sea conditions, and in laboratory buried-object (in sand) identification studies.INSTRUMENTATION: The MWM consists almost entirely of commercial off-the-shelf equipment. Antenna housings and polarization switching logic were designed and built at NRL.
