Track while scan

Track while scan

The track while scan (TWS) is a mode of radar operation, in which the radar allocates part of its power to tracking the target or targets while part of its power is allocated to scanning, unlike the straight tracking mode, when the radar directs all its power to tracking the acquired targets. In the TWS mode the radar has a possibility to acquire additional targets. [James Constant (1981) "Fundamentals of Strategic Weapons: Offense and Defense Systems", ISBN 9024725453, [http://books.google.com/books?id=wjVnisG_6KMC&pg=PA193&dq=%22track+while+scan%22&sig=y8uWevnMI3gAdPYAfPKN1i81AEM p. 193] ]

Unlike the straight tracking mode, TWS radars have to solve an additional problem of recognizing whether each target discrimination/detection defines a new target or belongs to already tracked targets.
