Apparatus and method for suppression of unnecessary signals in a radar system
By pulsing transmission radio waves of continuous wave radar, clutter components included in a reception signal are suppressed. In a radar system that emits into space pulsed transmission radio waves being generated based on a frequency-modulated reference continuous waveform, acquires a reception s...

description | By pulsing transmission radio waves of continuous wave radar, clutter components included in a reception signal are suppressed. In a radar system that emits into space pulsed transmission radio waves being generated based on a frequency-modulated reference continuous waveform, acquires a reception signal by receiving the pulsed transmission radio waves reflected from an external object, and computes distance thereto and velocity thereof from the frequency of a beat signal obtained by mixing the acquired reception signal with the reference continuous waveform, the radar system includes a frequency-band selector 19 for classifying, on the basis of a spectral spread corresponding to the pulse width of the pulsed transmission radio waves, frequency components of the beat signal, and a distance/velocity calculator 20 for computing, on the basis of the classified results from the frequency-band selector 19, relative distance to and velocity of a moving object, or relative distance to a stationary object. |
