radar resolution

radar resolution
Range resolution as a function of a pulse width. The smaller the beam width, the better would be the range resolution.

Radar resolution in azimuth is a function of beam width. Narrower the beam, better is the resolution.
The ability to distinguish between two closely spaced targets. The distance between two resolvable targets must be defined in each of the dimensions of measurement, which typically for a radar are range, azimuth, elevation, and velocity. Range resolution is determined by pulse width, whereas angular resolution is dependent on antenna-beam width. Velocity resolution is determined by Doppler processing.

Their study upends the belief that radar resolution is proportional to the bandwidth consumed.
The addition of more antennas enables increased radar resolution, which requires a corresponding increase in DSP performance, said Mike Demler, senior analyst at the Linley Group.
As for modern forecasting, Hausen said the recent launch of the Geostationary Operational Environmental Satellite (GOES) East satellite allows for higher radar resolution and the ability to map lightning density.
We think there's a certain utility there for Garmin Pilot users who need better radar resolution than FIS-B provides, plus weather that works reliably on the ground, and also want to see enhanced ADS-B traffic.
Suppose V = [[[V.sub.1], [V.sub.2], ..., [V.sub.n]].sup.t] is n samples of received radar signals in one radar resolution volume with sample time [t.sub.1], [t.sub.2], ..., [t.sub.n].
(ii) The spatial radar resolution must be sufficient to resolve the current signature.
Limited by the radar resolution, the errors of the m-D curve parameters obtained by HT or OMP are inevitable.

To complement this software package, the reader should also consult the companion text Radar Resolution and Complex Image Analysis and Theory and Practice of Radar Target Identification, available through Artech House, for the theory and more complete explanations.
In general, antenna size (or aperture) limits radar resolution. To get around space limitations, SAR uses a side-looking antenna and the fact that the aircraft is moving to synthesize a larger "virtual" antenna.
