Multiple Target Localization Using Wideband Echo Chirp Signals

Abstract

This work proposes a unique technique for wideband chirp signals-based detection and estimate of the range, velocity, and direction of arrival (DOA) of numerous far-field objects. A wide region is covered by the wideband signal that is created. The targets reflect them, and an echo signal is created. The range, radial velocity, as well as DOA of the echo signal are extracted to identify the objects. Using the LCT, the range, radial velocity, and DOA are determined. The main goals of the system under consideration are to transmit a wide band signal over an area, to detect targets nearby, to obtain an echo signal from a target that has been reflected, and to extract features from the echo signal, such as range, radial velocity, and DOA, in order to achieve superior performance metrics than previous ones.
