Bistatic radar signal processing often assumes a constant velocity for target detection. The bistatic geometry alters however the effectively measurable velocity in relation to the target position and motion even if the target has a constant ground speed. Hence, the bistatic geometry induces an instantaneous bistatic target acceleration. This is especially the case if a straight-line target trajectory cuts across several closely spaced velocity isolines. The letter tries to quantify this geometry-induced instantaneous bistatic acceleration in general for straight-line target trajectories. Thereby, position dependent acceleration values are derived for a practical use case.
