Abstract: Techniques are disclosed for detection and ranging systems and methods to improve range resolution, target separation, and reliability. A method includes selectively attenuating a signal representing a ranging system return or echo from targets so as to suppress side lobes or other undesirable artifacts appearing in the signal due to noise, interference, and/or distortion. A method may additionally or alternatively include rejecting interference events in ranging system returns by comparing a received return with that expected from a target illuminated by the ranging system, as determined by characteristics of its particular ranging sensor, and rejecting or attenuating returns or portions of returns that fail to match those characteristics in time or space.

Abstract: Various techniques are provided to securely pair devices using default connection information. In one example, a method includes storing, on a first device, a connection list comprising a plurality of connection entries. The first device selects a default connection entry in the connection list. A secure default connection is established between the first device and a second device using the default connection entry. Defined connection information is received at the first device from the second device over the secure default connection. The defined connection information is stored in a defined connection entry of the connection list. A secure defined connection between the first device and the second device is established using the defined connection entry.
