Recently, the Naval Research Laboratory conducted 95 GHz passive and active measurements of a variety of targets on land and water backgrounds. The 95 GHz receiver system used stepped vertical raster scans to acquire images at both vertical and horizontal polarizations in passive mode, and at VV (vertical transmit/vertical receive), VH, HV, and HH polarizations in the active bistatic mode. Since the system operated in either passive or bistatic modes, the vertical and horizontal passive images are time-coincident, and with a single polarization source, the VV and VH bistatic images are time-coincident, as are the HV and HH images. Thus, comparisons among the various type of millimeter wave data are obtained by revisiting a given scene, and comparing areas within an image. The targets used were trihedral corner reflectors ranging in size from 20 to 60 cm, metal spheres, flat plates and sheets of microwave absorber. With 0.5 meter resolution at a range of 100 meters, and a 0.25 degree kelvin noise temperature for 0.1 seconds averaging, the system imaged these small targets floating on the water, and viewed scenes behind tree foliage. Initial analysis of the data using one-dimensional Fourier theory has enhanced the detection of the small targets. Further, additional spatial information obtained using polarization contrasts suggests the presence of sub-resolution elements within the images that may be enhanced using beam-shaping techniques.
