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.
With FCM, raising the modulation speed enables detection with better distance resolution and a broader range of target-objects speeds.
The wide frequency coverage provides high-resolution distance resolution, so the handheld analyzer can conduct more accurate Distance-To-Fault (DTF) measurements.
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.
