A security sensor system comprises one or more laser detection and ranging (LADAR) sensors configured for accumulation of three-dimensional image data. In one embodiment, the one or more LADAR sensors each comprise a LADAR device, such as a MEMS device, configured to transmit a plurality of laser pulses, and a microprocessor operatively coupled to the LADAR device. One or more data storage devices is operatively coupled to the microprocessor and configured to store the three-dimensional image data, as well as predetermined protected area boundary and fixed object definitions. A GPS receiver can be operatively coupled to the microprocessor and a GPS antenna. The microprocessor is configured to perform a LADAR image analysis that compares the three-dimensional image data with the protected area boundary and fixed object definitions to identify one or more potential intruders.

Security system using LADAR-based sensors

One exemplary embodiment is directed to a method of automatically maintaining a line-of-sight communication channel. The method comprises determining information about each communication resource that is accessible in a region through which a mobile system is moving. The method further comprises determining information about the mobile system. The method further comprises performing a line-of-sight (LOS) analysis for each of the communication resources based at least in part on a respective location and a respective elevation for the respective communication resource and the current location of the mobile system and a current elevation for the mobile system. The method further comprises determining if a new communication link should be established with at least one of the communication resources based at least on the LOS analyses that were performed and establishing the new communication link if it is determined that the new communication link should be established.
