Dual-function radar–communications using sidelobe control

This chapter provides an overview of recent advances in radar-embedded communication signals. Several information-embedding techniques have recently been successful in establishing dual-function systems that simultaneously perform both radar and communication functions. Similarto single-function communication platforms, dual function systems should provide secure communications to protect user signals from being intercepted by other users or unintended receivers. Information embedding into the emission of multiple-input (MIMO) multiple-output radar provides a means for broadcast communications to be secondary to the primary radar function of the dual system.
