Channel Characterization Using Radar for Transmission of Communication Signals

Download Now Free registration required

Executive Summary

As radar and communication systems both are RF systems, a combination of both may be possible. The communication channel between transmitter and receiver is modeled and then adapted to include a rotating narrow beam antenna, common to radar systems, located at the transmitter side. Assuming an omni-directional antenna at the receiving station, this channel model can help to understand the similarities, differences and possibilities of the combination of radar and communication. Then the channel capacity is analyzed using this system setup. Whether this channel capacity can be approached or not depends on the channel realization and the possible presence of Doppler.
