distance resolution

[′dis·təns ‚rez·ə‚lü·shən]
(engineering)
The minimum radial distance by which targets must be separated to be separately distinguishable by a particular radar. Also known as range discrimination; range resolution.

A single-point model design standard is a contradiction between the measured minimum distance (2.1) and the distance resolution (2.2): small fs can measure more near objects, but larger fs can get higher distance resolution.
Key VRTS attributes include the ability to simulate Doppler effect velocity of up to 250 km/ hr, minimum obstacle range of 4 m, object distance resolution down to 10 cm, support for multiple angles of arrival, and variable radar cross sections.
Also, the distance resolution, [DELTA]z, depends on pulse width, [T.sub.pw], of the transmitted light pulse, as shown in (3).
With 1.5m distance resolution related with 1/bandwidth, when the two targets were placed at [R.sub.1] = 5 m and [R.sub.2] = 5.8 m, respectively, the range spectra for DFT, MUSIC, and the proposed method were derived as shown according to different SNR in Fig.
With FCM, raising the modulation speed enables detection with better distance resolution and a broader range of target-objects speeds.
The radial distance resolution of this radar is about 30 meters, compared to the field research [2] conducted in 2010, when the radial distance resolution of the short-range LIDAR was 75 meters.
An important improvement with this method is the exploitation of stripe flanks for improved triangulation accuracy: digital projectors and cameras allow to generate and measure 'gray value' gradients at extreme accuracy and deliver an improvement in triangulation and distance resolution by up to two orders of magnitude.
Using a short optical pulse produced by a crystal, semiconductor, or optical fiber laser, the SU-02-SPC can be used for ranging applications with a distance resolution as fine as five mm.
For previous OTDR's, best-case distance resolution is limited to the sample spacing.
The trade-off associated with using the windowing function is a reduction in the distance resolution of the main spike.
"By displaying the narrowest peak, the rectangular windowing is able to display more details for a given distance resolution, but it also displays the most side lobes for any given peak.
