Accordingly, our systems and products range from low-cost Scorpion Conventional Handheld Radios, to advanced TETRA Digital Trunked Radio Systems. Furthermore, noise, although other assumptions can be made as in [71, 72, 208]. extended to the case of multiple antennas. Available in all standard shell materials and plating options, Molex’s MXL38999 uses Molex’s LumaCore™ optical terminus technology. The surface surveillance radar (Seastar) was developed especially for this purpose and it is capable of detecting and tracking small objects (e.g. divers' head) between the waves, contributing enormously to situational awareness in littoral environments.

The numerical scheme utilizes a control-volume approach with a variable grid to account for surface movement. This method directly supports implementation of nontraditional models such as material swelling and mechanical erosion, extending capabilities for modeling complex ablation phenomena.
