MIMO vector radio channel sounding devices allow multidimensional analysis of wave propagation in mobile radio channels. 6-dimensions represent Doppler, TDOA, 2-D DOD and 2-D DOA. Antenna array architectures, calibration and K-D unitary ESPRIT parameter estimation are discussed. Parametric channel models can be derived from the estimated data.

The ionosphere can make the short-wave source localization problem further non-linear, leading to a complicated solution process. This paper proposed coordinated positioning algorithm based on ionospheric virtual height (IVH) model jointly estimate target position and reflection using direction of arrival (DOA) time difference (TDOA) measurements. method is divided into two stages, first stage ...

This paper develops the model of joint phantom track deception and techniques time-difference arrival (TDOA) frequency-difference (FDOA) localization to deceive air defense radar networks under condition that an unmanned aerial vehicle (UAV) swarm has no prior knowledge radars’ precise locations, related performance experiment analysis are presented demonstrate effectiveness proposed method cla...
