A program of High Angular Resolution observations of stars and their circumstellar regions using the technique of lunar occultations has been initiated at the 1.2 m telescope at Gurushikhar (24°39′ N, 72°47′ E), India. A liquid nitrogen cooled InSb detector based high speed Infrared photometer with millisecond data acquisition capabilities has been ...

A two multi-r o telescope interferometer was built at Air Force Research Lab in Albuquerque New Mexico as a development testbed. The principal objective of this testbed is to develop existing techniques and to test novel low-cost technologies for applications in future interferometers. These technologies include a tip/tilt piston mirror that has a 500-

High Angular-Resolution Techniques
2009This chapter examines the synthesis and performance of one-dimensional (1D) and two-dimensional (2D) phased arrays and their application in sonar and radar before considering the elegant algorithms for Doppler beam sharpening and synthetic aperture radar (SAR) that can be used to produce a 'beam' with no divergence at all.
