What is stepped frequency continuous wave radar?

The SFCW is a radar technology that uses the frequency diversity to detect a target based on its answer to the microwave signals for each discrete frequency.

What is stepped 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 used an inverse Fourier transform of these data to build a time domain profile (A-scan).

What is the difference between CW and pulsed radar?

A pulse radar needs high peak power to achieve sufficient average power, while in a CW radar the peak power is equal to the average power. This is why CW radars use low-power transmitters, based on low-voltage solid state devices rather than on high-voltage vacuum tubes.

What is continuous wave Doppler radar?

Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects.
