Abstract

The report gives an overview of possible use of doppler radar for measurement of various kind of movements in local battlefield surveillance in urban environment. The expected targets are both humans as well as non-biological objects like vehicles, machines, bullets. Special attention is given to so-called micro-doppler, i.e. movement of target parts (breathing, heartbeat, gait, vehicle tracks etc), which may be superimposed on a global movement. Examples are given of recordings of such types, both from international work and from the FOI. The wave propagation in the complex background environment is pointed out as the foremost difficulty in connection with the signal analysis. The possibility of using noise as signal form (noise radar) is described, with an account of the work done in the project. Possible approaches and parameter choices are sketched in an overview for the subsequent FOI activity for working out a system concept of a hand-held doppler radar.
