Abstract
Frequency calibration of a bi-static type of radar system is performed by positioning radar transmitter and receiver in spaced relation to each other over a targeted seawater surface from which radar radiation along a forward radiation scattering path is reflected toward the receiver while radar energy is also radiated along a direct path to the receiver by-passing the seawater during sequential frequency measurement tests to determine a frequency diffraction factor. A radiation blocking barrier is positioned by a floating support at a reflection location at an angular position on the seawater surface for intersection by the forward scattering path to block reflection of radar energy radiation toward the receiver during one of the measurement tests.
