Cognitive radar for waveform diversity utilization

In this paper we discuss the relationship between cognitive radar and waveform diversity. The cognitive decision-making process selects the most appropriate waveform from the available set of diverse waveforms based on a perception of the current environment and scenario, thus creating a perception-action cycle (PAC). This combination of waveform diversity and cognition does not just improve performance, it is becoming critical for realizing modern radar systems due to increasingly challenging operating environments. Therefore, the robust techniques proposed in this paper can be highly valuable for enabling enhanced PACs in radar systems.
