Five stationary point scatterers are assumed in the scene, and the imaging result without phase compensation is shown in Fig.
Further, a point z [member of] X is called a stationary point (or endpoint) of S and T if Tz = {Sz} (see [10]).
To answer these questions, one may examine the formula for the value of [epsilon] at the stationary point of Lagrangian L.

The fact that the correlation function of a stationary point process depends only on the difference of the locations u and v and not on the locations themselves is an important property of the stationary point processes.
Because we're basing our descent on a stationary point, such as a fix or an airport, using groundspeed for all estimations is key, because it takes into account any and all variables.
