1. An unmanned vehicle (UV), comprising:
an ultra-wide band (UWB) transceiver sensor including an S-band, multiple input multiple output (MIMO) phased array radar system configured to detect a presence of an object in an area;
a sub-gigahertz UV data link transceiver configured to wirelessly communicate location information regarding the object detected from the S-band, MIMO phased array radar system to a controller;
an inter-UV data link transceiver configured to wirelessly communicate the location information to a second UV and to receive, from the second UV, a detection message at the inter-UV data link transceiver confirming the location information; and
a UV local positioning system configured to:
receive one or more local positioning signals from a plurality of local positioning system portable antennas surrounding the area;
determine a time delay of each of the one or more local positioning signals received by the UV local positioning system, each time delay relative to a particular local positioning system portable antenna and calculated based on a time difference between transmission of a local positioning signal by the particular local positioning system portable antenna and receipt of the local positioning signal by the UV local positioning system;
determine a distance from the UV to each of a subset of the plurality of local positioning system portable antennas based on the time delay of each of the one or more local positioning signals; and
determine a localized position of the UV in the area based on the distance from the UV to each of the subset of the plurality of local positioning system portable antennas.
