摘要：

A new very high-frequency compact radar range has been developed to measure scale models of tactical targets. This compact range has demonstrated very good signal-to-noise and is useful in measuring low observable targets. In addition to normal ISAR imaging of targets (range vs. horizontal cross-range), the system can also produce two-dimensional images in azimuth and elevation (vertical cross-range vs, horizontal cross-range). The 1.56THz transceiver uses two high-stability optically pumped far-infrared lasers, microwave/laser side-band generation for frequency sweep, and a pair of Schottky diode receivers for coherent integration. Measurements made on 1/16th scale models of tactical targets, simulating W-band frequencies, allows the formation of images of very high cross-range resolution (3.5cm full scale) while still integrating over a reasonably small angular extent (2.5degrees). The results from several targets that have been recently measured will be presented.
