What is step-frequency?

Step-frequency is a radar waveform consisting of a series of sine waves with linearly increasing frequency.

The radar measures the phase and amplitude on each frequency and uses an inverse Fourier transform of this data to build a time-domain profile (A-scan). Thus, the step-frequency radar collects data in the frequency domain and converts the data to time-domain data through computer processing.

The step-frequency waveform gives the optimum source signature with a uniform frequency spectrum. The computer control allows the user to set the dwell time on each frequency as well as the start and stop frequencies.
