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 have angle of arrival of target return, which is obtained using beamforming. The beamforming technique can also enhance signal to disturbance ratio. However,...
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 beamforming method facilitate real time tracking of small to moderate size targets in real Cartesian domain. The results have been validated through...
We investigate the performance of a Bucci based beamformer design and MUSIC algorithm under a passive radar setup using experimental measurements. A uniformly spaced linearly array of 11 discone antennas was used for the passive radar. The experiment was performed by exploiting the DVB-T broadcasting station as the illuminator of opportunity. In order to suppress the direct reference signal and clutters,...
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 authors’ propose a new approach to balance SINR of users in various cells to different maximum possible values. This has the ability to allow users in...
We propose a coordinated multicell beamformer design method based on the signal-to-interference-plus-noise ratios (SINRs) balancing technique within the context of mixed quality of services (QoS). Instead of attaining an overall balance of SINRs to all users in all cells, the proposed algorithm allows a specific subset of users in each cells to achieve certain target SINRs while the SINRs of the remaining...
