Haystack Radar

This 'Planetary Radar Box' at the Lincoln Laboratory's Haystack Microwave Research Facility was developed to perform long-range interplanetary radar measurements, including those needed to carry out a new 'fourth test' of Einstein's theory of general relativity.  In this picture, the box is shown in a test stand on the ground, preparatory to being hoisted up and 'plugged in' behind the Haystack antenna.  The structure projecting from the front face of the box is the feedhorn used to transmit radar pulses and received radar echoes from the planets Venus and Mercury at distances as great as 160 million miles. The Haystack Microwave Research Facility has been developed and operated by the M.I.T.
