Abstract
A multistatic backscatter system may comprise unsynchronized devices. The unsynchronized device may comprise two or more spatially separated transmitter devices to transmit carrier signals, a transmitter device being configured to transmit carrier signals over a frequency set of two or more different frequencies; at least one backscatter device configured to frequency-shift the carrier signals, modulate data on at least some of the carrier signals, and backscatter modulated frequency-shifted carrier signals as backscatter signals, and at least one receiver device configured to receive the carrier signals and the backscatter signals, to process them to obtain the data and determine ranging information for the backscatter device.
