Applications of submillimeter wave technology for SDI
This paper examines the potential use of using submillimeter wave technology (actually 3 mm to 100 microns, or frequencies between 100 GHz and 3 THz) for SDI applications, especially for endo-KEW systems. The requirements and functions for a multipurpose weapon sensor are considered. The emphasis is on active sensors, but certain elements of passive sensors are mentioned that could play an important role. The rest of the paper provides information on the state-of-the-art in submillimeter wave technology, especially current component activity, and future plans.

A grid amplifier
A 50-MESFET grid amplifier is reported that has a gain of 11 dB at 3.3 GHz. The grid isolates the input from the output by using vertical polarization for the input beam and horizontal polarization for the transmitted output beam. The grid unit cell is a two-MESFET differential amplifier. A simple calibration procedure allows the gain to be calculated from a relative power measurement. This grid is a hybrid circuit, but the structure is suitable for fabrication as a monolithic wafer-scale integrated circuit, particularly at millimeter wavelengths.

Reaction time to changes in the tempo of acoustic pulse trains.
Investigation of the ability of human observers to detect accelerations and decelerations in the rate of presentation of pulsed stimuli, i.e., changes in the tempo of acoustic pulse trains. Response times to accelerations in tempo were faster than to decelerations. Overall speed of response was inversely related to the pulse repetition rate.
