What may affect the angle of arrival calculation in the RSDS but will not impair signal detection?

• A. Aircraft speed
• B. Altitude
• C. Attitude and angle of attack
• D. Weight distribution

Answer: (C)

The angle of arrival calculation in the Radar Signal Detection System (RSDS) is influenced by the aircraft's attitude and angle of attack due to their direct impact on the orientation of the aircraft relative to incoming signals. This means that when the aircraft is in different attitudes or experiencing various angles of attack, the way it receives radar signals can shift, affecting the perceived angle of arrival. Importantly, while changes in attitude and angle of attack can alter the calculated angle at which signals are received, they do not impede the ability to detect those signals. This distinction is crucial, as detection remains unaffected even if the calculation of angle arrival becomes less accurate. In contrast, other factors like aircraft speed, altitude, and weight distribution can also influence the operational dynamics of the aircraft but do not have the same direct effect on signal computation in the context of radar systems.
