the effect of temporal baseline on coherence

In general the long temporal baseline in vegetated area, or unstable objects within same area affects the coherence correlation between two or more passes,

This matter is discussed here,

DEM creation

@ryeramirez

and perpendicular baseline in coherence

Here also is good explanation

Sentinel 1 per. & temp. baseline

Some example of articles,

Impact of Perpendicular and Temporal Baseline Characteristics on InSAR Coherence Maps

The effect of the perpendicular baseline on coherence for SAR images in InSAR

Also it is explained well in here
