OVERVIEW: The CROSS ROUND aka MR352 Pozitive-ME1.2  is a shipborne 3-D, air and surface search and target designation radar operating in the I/J band (active) (NATO).

DETAILS: The CROSS ROUND uses a planar array antenna using phase/frequency scanning, with an IFF antenna along its lower edges.  It features  a high-speed rotation and  electronic elevation scanning, to provide a short reaction time, high throughput capacity and target designation capability. It is capable of tracking up to 40 targets simultaneiously, and can lock onto a designated target in 3.5 seconds.
