Abstract : A Millimeter-Wave Study has been in progress at HDL to investigate atmospheric phenomena and possible ranging applications at millimeter-wave frequencies. Major effort has been directed toward designing and evaluating a 70-Gc radar detection unit that would enhance target identification with minimized size, weight, and power consumption. This study was temporarily suspended, however, before completing the program objectives. Therefore, in addition to presenting a description of the unit and its performance, this report also outlines certain design improvements that are considered applicable in a further developmental program. The unit under development is self-contained in a rectangular volume 2800 cu. in. including the antenna, weighs less than 25 lb, and operates continuously for 1 hr on its internal battery; it has an antenna beamwidth of less than 0.6 deg and a total power consumption of approximately 100W. The system is constructed to measure range and atmospheric attenuation (Absorption), based on elapsed-time indications and variations in signal-path attenuation. By using an optical arrangement that is aligned with the radiated beam from a common transmit and receive antenna, the operator has a visual and electrical presentation of the field of coverage.
