WebIt is shown that it is possible to choose an optimal integration time for a given application. A relatively straightforward procedure is given to determine this optimal value. The results are confirmed through Real Time Kinematic (RTK) processing of live satellite signals. Key Words: GNSS, ultra-tight integration, coherent integration time, Kalman WebTo achieve coherent integration, many successful methods have been proposed [14–16]. In this paper, the KT is employed for convenience, which scales the slow time for each range frequency: Substituting the scaling formula into (20), we get By equation (22), the coupling caused by the ambiguous velocity is removed.

WebA widely applied coherent integration method is moving target detection (MTD) [ 6 ]. The radar’s range units are relatively small in wideband radar observation; therefore, even a slowly moving target’s range walk will exceed several range units. This type of across range unit (ARU) will limit the integration time for MTD.
