What factor significantly impacts the magnitude of the Angular effect in RADAR systems?

The magnitude of the Angular effect in RADAR systems is significantly influenced by how the RADAR device is aimed or pointed. The Angular effect refers to the phenomenon where the measured speed of a moving target can vary based on the angle at which the RADAR beam strikes the target. When the RADAR is not aimed directly at the moving object, the speed is calculated using only the component of the target's velocity that is aligned with the radar beam, leading to an apparent reduction in the speed measurement. This relationship illustrates the geometry involved in the interaction between the radar signal and the moving target.

When the RADAR device is pointed directly at the target, the measurement more accurately reflects the target's true speed. Conversely, when the angle is oblique, the resultant speed reading can be significantly lower than the actual speed of the target, emphasizing the importance of correct aiming.

Other factors, such as the distance of the target object, the speed of the moving object, and the type of RADAR technology used, affect the overall operation of the RADAR system but are less directly tied to the Angular effect itself compared to proper aiming. Hence, the angle at which the RADAR beam interacts with the target is crucial for accurate speed measurements.
