resolution"1. The degree to which nearly equal values of a quantity can be discriminated. 2. The smallest measurable change in a quantity. 3. The least value of a measured quantity that can be distinguished. 4.
RESOLUTION In relation to radar, it is the ability to read two distinct targets separately. The clearer the resolution, the nearer the two objects can be to each other and still be distinguishable.
Resolution The degree to which a radar distinguishes detail in a spatial pattern.
Response Time The amount of time in which it will take a watershed to react to a given rainfall event.
RESOLUTION: The smallest change in the parameter being measured that causes a detectable change in the output of the instrument.
RESPONSE: The value of the quantity being measured as indicated or otherwise provided by a measuring instrument.
resolution—Pertaining to radar, the ability of radar to show discrete targets separately, i.e., the better the resolution, the closer two targets can be to each other, and still be detected as separate targets.
Resolution A measure of the ability to separate observable of an image. The smaller the area represented by a pixel, the more accurate and detailed the image. APT has a resolution of 4 km, i.e., each pixel represents a square, 4 km on each side.
Range Resolution
The ability of the radar to distinguish two targets along the same radial but at different ranges. it is approximately ?Ǭ? the pulse length.

Pulse Resolution Volume: A discrete radar sampling volume, of dimensions (horizontal beamwidth * vertical beamwidth * 1 range gate).

The dynamics of such systems are not fully understood, and it is only with the (recent) arrival of very high-resolution satellite imagery & sensors in a wide variety of spectral bands that the detail within such systems can be studied.
In addition, severe storm modelers have begun using high-resolution forecast models to predict severe weather. These models are initialized with a wide variety of observational data that reflect the character of the current atmosphere.
The sum of all backscattering cross-sections (e.g., precipitation particles) in a pulse resolution volume divided by that volume.
This mode is designed to provide higher resolution for relatively strong echoes so the radar becomes less sensitive. It generally utilizes VCP21 and produces an image every 6 minutes.
