Its only hindrance is its limited angular resolution, while LIDAR's only benefit is its angular resolution.
The high angular resolution of laser radars broadens these system applications to include radar imaging.
However, by using the AMBER interferometry instrument to simultaneously combine the light from three 8-meter telescopes at the Very Large Telescope Interferometer (VLTI) at the Paranal Observatory in Chile, the research team was able to achieve the angular resolution needed to observe the hot dust ring.
The angular resolution is derived from the scanning of the antenna beam, and the range resolution is from the return of pulses from everything that reflects the pulses.
This method, however, is not suitable for distant galaxies because of the extremely high angular resolution it requires.
The new atlas needed more than 4,500 hours of observations to compile, and its angular resolution is similar to that of the 21-cm wavelength survey of the Milky Way obtained at the 100-metre radio telescope at Effelsberg.
High-Energy Sky "Now that we have a feeling for the low angular resolution of present-day detectors we can study the appearance of the gamma-ray sky.
Similarly, ground target acquisition systems could be built using MMW technology.(6) The narrow beam-width of MMW systems would seem to limit its application to threat warning unless the MMW system was cued by another wide-view sensor; then, the narrow beam would be an advantage, providing excellent range and angular resolution performance.
