Radar, "peeping" for the building, will be able to track vehicles in complex urban environments

Radar technology have become an ideal tool for calculating and tracking of specific goals, both in the sky and the sea, where the radar beam from nothing to hide. However, the use of radar in urban areas is associated with a number of problems hindering the performance of all radar system. Recently it was reported that the Office of Research Programs Pentagon DARPA, was engaged in developing a new technology that allows you to use different planes of buildings as reflectors of the radar beam. Such "smart" system will be able to easily keep track of any transport, including the one found in dense traffic flows that move between the high-rise buildings, skyscrapers, and many other outdoor structures.

The system, called Multipath Exploitation Radar (MER), uses the surfaces of buildings as mirrors, reflecting the radar beam and the reflected signals, so that it will be possible to "look" around corners and facilities that will allow for maintenance purposes, even if this The unibody is a clear line of sight. Such opportunities MER system gives her two-component system. The first component is the technology of optical scanning LIDAR, which is compiled with the help of three-dimensional model of the space being monitored. Using this model, the system calculates all the angles of reflection and finds a point in space from which it would be best to observe the purpose of using the reflected signals.

Using radar Ku-band system MER is sensitive to even small differences objects, thus allowing to distinguish two different cars of the same brand. This guarantees that the observation is not to be lost in a transport stream and in a multiple signal reflections from buildings. Are currently underway to develop a new, reinforced system of laser scanning LIDAR, on completion of which the MER system will be able to cover their eyes with a height of an area of 965 square kilometers. It is also developing new algorithms for calculations of position in space, through which it will be possible to carry out tracking of multiple targets simultaneously.
