WebA form of pulse radar that uses the Doppler frequency shift to eliminate stationary clutter is called either a moving-target indication (MTI) radar or a pulse Doppler radar, depending on the particular parameters of the signal waveform. The above measurements of range, angle, and radial velocity assume that the target is a “point-scatterer.”. Web30 jun. 2024 · The generally-accepted definition of radar resolution is the width of the IPR at points at 3 dB below the peak of the IPR. In the range dimension, a larger transmitted bandwidth corresponds to improved range resolution. In the cross-range dimension, a larger Doppler bandwidth corresponds to better azimuth resolution.
