Will flying over rough sea activate memory mode in a Doppler navigation system?

In a Doppler navigation system, memory mode is typically activated based on specific conditions that are not related to the type of terrain being flown over, such as rough seas. Memory mode is primarily designed to maintain a track or store data from smooth, consistent conditions that enable easier navigation and processing of information.

When flying over rough seas, the Doppler radar can experience significant fluctuations in returns due to the motion of the waves and the instability of the surface beneath. This can cause the system to experience difficulties in determining a stable reference point for navigation, thus making activation of memory mode less likely. Instead, the system relies on continuous updates and may not retain a consistent enough signal to switch to memory mode.

Other factors like visibility and wind strength can impact navigation but do not influence the primary functionality leading to the activation of memory mode in this context, as the operational capabilities depend on consistent surface tracking rather than environmental conditions like visibility or wind alone.
