OVERVIEW: The Martello S-723  is an long range, transportable 3D surveillance radar system designed for world-wide use in military applications, operating in the D-Band 

DETAILS: The S-723 is a planar array, consisting of a stack of 40 linear arrays and is rotated at six revs/min about a vertical axis to provide all round surveillance. Each linear array is fed with R.F. modules power from its own solid states power amplifier module.
