In this letter, air-induced passive intermodulation (PIM) modeling and cancellation schemes are presented in a multiple-input multiple-output (MIMO) frequency-division duplexing (FDD) transceiver c
The increasing complexity and speed of modern commercial and military aircraft require assistance to the pilot in informing him of rapidly changing conditions.
We demonstrated an all-fiber variable attenuator using a tapered ASME Efficient modal field interaction between the propagating mode and tunable materials infused into the air-holes of the fiber re
In previous studies we have measured the airborne concentrations and surface accumulation rates of ionic substances at electronic equipment installations.
Sampling and analysis methods for characterizing vapor phase organic compounds in clean rooms have been developed.

The ILS-2 system [see Abstr. 1950B03078 is summarized and the problem of sensitivity of airborne equipment is discussed.
Airborne sonar target recognition involves two key technical issues: target feature extraction and classification.
The equipment is designed to receive range and bearing information from a ground-based Tacan beacon.
A system of d.c. output 800 A, 30 V under varying temperature and humidity conditions with a reasonably small amount of air-blast cooling is described.
