Abstract:

A MICrowave RADiometric MICRAD guidance system is disclosed which utilizes an antenna having four beams, designated right, left, up and down. Information from the four beams is monitored essentially 100 of the time by passing through appropriate ferrite cross-switching means to four separate receivers. Information from two of the receivers passes through a first multiplexer and feedback gain balancer to provide a target azimuth output, and information from the remaining two receivers passes through a second multiplexer and feedback gain balancer to provide a target elevation output. A local oscillator heterodynes each of the four receivers in common, and a switch driver couples each of the multiplexers to the ferrite cross-switching means and gain balancers for appropriate selection.
