Abstract: A radar system that includes a gimbal and a platform secured to a frame through the gimbal is disclosed. The radar system includes an antenna rotatably supported by the platform for rotation about an axis and configured to scan a hemispherical field of view above the platform. A controller that controls the rotation of the antenna and a gyroscopic stabilizer that is secured to the platform to maintain the platform in a stable and level position during operation of the radar system and rotation of the antenna is also disclosed. A vehicle is also disclosed for traversing a geographic region with the radar system. The antenna may transmit in the X band. A telescoping mast having a first end secured to the platform and having a second end secured to the gimbal is also disclosed.

Abstract: A method of positioning a plurality of radar units in a defined area amongst one or more legacy radar units that provide legacy radar coverage in the defined area is disclosed. The steps of identifying a location of each legacy radar unit, setting a threshold altitude, and determining a legacy occultation of each legacy radar unit from a landscape level up to the threshold altitude are also disclosed. Mapping the legacy occultation of the legacy radar units to provide a three dimensional occultation map in the defined area and locating gaps below the threshold altitude in the legacy radar coverage as a function of the occultation map are also disclosed. Identifying a plurality of sites as a function of the gaps where the sites are accessible to receive a radar unit is also disclosed. Determining an anticipated radar coverage of a radar unit positioned at each of the sites and determining a reduction in the gaps as a function of the anticipated radar coverage are also disclosed.

Abstract: A system and method for communicating with a plurality of emergency response persons is disclosed. A plurality of portable communication devices are provided for the emergency response persons. A central station including a video monitor and a video camera is in communication with a network. A plurality of remote stations including a video monitor and a video camera are also in communication with the network. The central station is in communication with the portable communication devices to provide a message to the emergency response persons. The remote stations are positioned for access by the emergency response persons. A router is in communication with the network for providing a bridged video connection between the central station and the remote stations. Emergency response persons located adjacent the remote stations are in video communication with each other and the central station.
