The unpredictable noise in received signal strength indicator (RSSI) measurements indoor environments practically causes very high estimation errors target localization. Dealing with RSSI and ensuring target-localization accuracy RSSI-based localization systems is a popular research trend nowadays. This paper proposed two range-free schemes wireless sensor networks (WSN) for an setup: first pla...

In the case of through-the-wall localization of moving targets by ultra wideband (UWB) radars, there are applications in which handheld sensors equipped only with one transmitting and two receiving antennas are applied. Sometimes, the radar using such a small antenna array is not able to localize the target with the required accuracy. With a view to improve through-the-wall target localization,...
