Biomimetic target localisation using an EMFi based array

Bats are known to use spectral cues to localise targets. We propose a similar localisation scheme making use of a sensor array built using EMFi material and a structured backplate. We present an adaptation of `delay and sum?? beamforming that when combined with a broadband chirp results in accurate localisation (??2??) in a broad field of view [??70??,70??].
