Abstract

There is a growing need for bold and new concepts with the potential to contribute towards significant improvements in the efficiency of radio spectrum utilization and protection from interfering services. One of the most pressing problems in the area of spectral congestion and dynamic frequency allocations is to provide uncontested shared bandwidth between radar and communications. This has recently spurred extensive efforts towards devising solutions for simultaneous operations of radar target illuminations and wireless services sharing the same frequency bandwidth. Unlike the general approach of coexistence, which predicates on cognitive radio and cognitive radar for spectrum sensing and utilization, recent research is moving to enable the embedding of communication signals into radar waveforms. In so doing, the communication systems capitalize on the resources of existing radar infrastructure, including high power, large bandwidth, and high-quality hardware. This tutorial establishes and promotes the area of dual system functionality, allowing the radar to house voice and data transmission, leading to technological advances in radar and communications systems. The tutorial develops novel signaling schemes for embedding information into the radar pulsed emissions which, in most cases, is blind to the primary radar operation and radar ambiguity function. It considers different antenna configurations, including multiple-input multiple-output (MIMO) radars and shows how to achieve high data rate communications by combining amplitude-shift keying, phase-shift keying, and code shift keying modulations with waveform-diversity and spatial degrees of freedom.
