Radio-frequency (RF) signal analysis includes slow-time signal processing and fast-time signal processing. Incoming RF pulses are captured according to a resource scheduling configuration. The fast-time signal processing is to prioritize the captured RF pulses for slow-time signal processing based on dynamic pulse-grading criteria. The slow-time signal processing is to perform relevance evaluation of the prioritized RF pulses, and to adjust the dynamic pulse-grading criteria and the resource scheduling configuration based on the relevance evaluation.
