OVERVIEW: The SQUARE TIE aka Type 352 aka Type 331 aka Rangout aka MR-331 aka H/LJQ352 radar is a shipboard, short-range, 2-D, surface search and target acquisition  radar operating in the I-Band (NATO)(IEEE: X-band).  

DETAILS:     SQUARE TIE is a small, lightweight, short-range, air and surface search radar operating in the I-band. The system's antenna is an elliptical paraboloid reflector illuminated by an overhung horn feed. Functions include target detection and tracking for anti-ship missile direction.  The SQUARE TIE radar is  associated with the SS-N-2C ASM.
