Abstract:

The objective of the present program has been to show feasibility of miniature 35 GHz integrated circuit radiometers for operation in multichannel sensor arrays. The significant achievement of this work has been to successfully demonstrate low noise figure performance for integrated circuit radiometers over large IF bandwidths using miniature, low-cost microstrip circuit structures. In addition, the potential feasibility of large multichannel sensor arrays has been shown using two miniature receiver elements and a single sub-harmonic common local oscillator. An equally significant result has been the demonstration of high receiver gain stability for these sensors over video bandwidths extending from 0.01 Hz to 2500 Hz. Noise figure data taken on the receivers developed in this program approach 6.5 dB dsb for 600 MHz IF bandwidths, including IF preamplifier noise figures of 2.5 dB.
