We investigate effects of transmitter imperfections in terms of time and frequency offsets on the performance of digital video broadcast-terrestrial based passive radars. To facilitate an accurate reconstruction of the transmitted waveform, transmitt

This study investigates the causes and effects of signal mismatch on the performance of a passive bistatic radar that employs reference signal reconstruction processing on a moving receiver platform. In addition to the transmitter's imperfections, na

The authors propose a coordinated multi-cell beamforming technique for signal-to-interference plus noise ratio (SINR) balancing under multiple base station power constraints. Instead of balancing SINR of all users in all cells to the same level, the

We investigate the capability of beam space transformation based Direction of Arrival (DoA) estimation algorithms and an auto calibration method for the application in passive radar systems using real field measurements. For this, we considered three
Suitable methods to jointly exploit the diversity of information conveyed by different polarimetric channels in Passive Coherent Location (PCL) systems are a topic of current research. Possible signal processing strategies were devised for FM radio b

We propose a new precoder design technique for a cooperative base station (BS) and relay station (RS) network. The proposed approach provides substantial reduction in terms of transmission power for a given set of target user rates as compared to a s

We propose a two stage beamforming technique for localisation of moving target in a passive radar environment. In order to perform localization and tracking in Cartesian plane, in addition to detection in the range Doppler domain, it is necessary to

We demonstrate the ability of a passive radar system to monitor a large area of interest by applying advanced multipath clutter cancellation algorithm, spatial beamforming and tracking techniques. The mitigation of clutter disturbance and a two stage
