What is a radar waveform?

1.1 Introduction. A radar waveform is a signal defined in time, frequency, space, polarization, and modulation with the purpose of eliciting desired information from the illuminated environment.

How does continuous wave radar work?

CW radar can measure the instantaneous rate-of-change in the target's range. This is accomplished by a direct measurement of the Doppler shift of the returned signal. The Doppler shift is a change in the frequency of the electromagnetic wave caused by motion of the transmitter, target or both.

What is radar signal processing?

The signal processor is that part of the system which separates targets from clutter on the basis of Doppler content and amplitude characteristics. In modern radar sets the conversion of radar signals to digital form is typically accomplished after IF amplification and phase sensitive detection.
