The spectral containment of active radar emissions is of growing concern due to continued erosion of allocated radar spectrum and the increasing congestion driven by consumer demand for bandwidth-gluttonous wireless video applications. Strict new emission requirements are forcing the careful consideration of how to achieve radar spectral containment within the context of the ever-present pressure for enhanced sensing performance. It is thus imperative that a holistic perspective be taken that addresses the characteristics of the physical signal launched from the radar, inclusive of electromagnetics, systems engineering and signal processing attributes. This chapter introduces recent developments on the design and implementation of physical radar waveforms for spectral containment, including experimental results for various new emission schemes.
