  • Abstract
    An analytical expression is presented for calculating the effects of multipath on group delay. The expression was experimentally verified by the tests made at the Telecommunications Development Laboratory of the Jet Propulsion Laboratory using the Mariner Venus/Mercury 1973 radio frequency subsystem, block 3 receiver, and the Mu 1 ranging machine. The motivation for the research is explained, and the results are put in the context of other applications to antenna and time-delay measurements.<>
