Abstract: Various embodiments that pertain to surface non-uniformity detection through use of radio waves are described. A vehicle can transmit radio waves to an area the vehicle is traveling to, such as a road in front of an automobile. The automobile can receive and process returned radio waves to determine if the road has a non-uniformity, such as a significant pothole or speed bump. If the road has the non-uniformity, then a driver of the automobile can be alerted so the driver can decide if evasive action should be taken and take such action if appropriate.

Abstract: A first frequency agile waveform and additional frequency agile signal waveform(s) having in-phase and a quadrature phase components, each shifted by a different delta frequency, are transmitted in the direction of a possible dispersive target. Return signal(s) each comprising an in-phase component and a quadrature phase component associated with each of the frequency agile waveform(s) are received. The return signal(s) associated with the frequency agile signal waveform(s) are phase shifted by their respective delta frequenc(ies). A combined return signal is generated by combining the first return signal and the additional phase shifted return signal(s). A probability of a potential target is determined when the combined return signal exceeds a threshold.

Based at least in part on the request, the content delivery platform can identify a target location, which may be the location of the mobile device, or some other location indicated in the request. A mobile device can be provided content based on the relationship of the target location to the geographic areas, so that a registered application running on a mobile device with a target location contained within a geographic area assigned to a particular sponsor will receive content related to that sponsor.
