• A microwave small area localization method based on compressed sensing system is proposed, which works with scattering source at 10 GHz-20 GHz. Three wide-band microwave source antennas are set up and generate scattering fields through obstacles to form a random field in the positioning area. As obstacle reflection, electric field distribution is sufficiently random. Combined with compressed sensing algorithm, target point position can be restored by measured scattered electric field value. Considered the operating frequency band, target is located in a 4 cm-width square area at a distance of 3 cm from the antenna. Positioning accuracy of the system is 1.4 mm when it works at a plate with the sizes of 11 cm× 10 cm. So it can be applied on finger positioning or situations that require a small range of precise wireless positioning. This method has the potential to be used on portable and wearable electronic devices.
