KISS FFT converts a time-domain signal (a series of samples from a microphone, ADC, accelerometer, etc.) into the frequency domain, revealing which frequencies are present and how strong each one is.

Abstract: Frequency Agile (FA) radar achieves superior antijamming capabilities by modulating the carrier frequency across different pulses. However, the array manifold changes with the carrier ...

Abstract: Owing to the escalating spectrum congestion and the rapid advancement of sophisticated active coherent jamming techniques, traditional radar systems with constant pulses exhibit limited ...
