摘要： In one embodiment, a method includes providing instructions to broadcast a modulated radar chirp signal from a radar antenna of a vehicle. The modulated chirp signal includes data associated with the vehicle. The method includes receiving a first return signal whose waveform substantially matches the modulated chirp signal. The first return signal is the modulated radar chirp signal after reflecting off of an object in an environment surrounding the vehicle. The method includes calculating a location for the object using the first return signal, receiving, from a base station antenna, a second return signal that indicates the modulated chirp signal was received by the base station antenna, and providing instructions to establish a wireless communication session with the base station antenna.

摘要： A symbiotic radar and communication system is disclosed. The system includes a plurality of base stations in communication with a wider communication network, each base station being configured to transmit and receive communication signals to and from a plurality of user terminals. The system performs communication data processing and radar data processing on received signals so that target object reflections contained therein can be resolved. Preferably, initial radar data processing is performed at each base station which embeds time and position information into the data and communicates it to a central radar server, the central server combining the received data from several of the base stations into a single range resolution profile.

摘要： Disclosed herein are a number of example embodiments that employ controllable delays between successive ladar pulses in order to discriminate between “own” ladar pulse reflections and “interfering” ladar pulses reflections by a receiver. Example embodiments include designs where a sparse delay sum circuit is used at the receiver and where a funnel filter is used at the receiver. Also, disclosed are techniques for selecting codes to use for the controllable delays as well as techniques for identifying and tracking interfering ladar pulses and their corresponding delay codes. The use of a ladar system with pulse deconfliction is also disclosed as part of an optical data communication system.
