🔍 Key Concepts

• PPI (Plan Position Indicator) radar displays show both moving and fixed targets • Discriminators / second detectors can be used to filter out certain types of echoes • Difference between returns from stationary objects (clutter) and moving targets

💭 Think About

• Which component or method in radar systems is specifically used to separate moving targets from fixed background echoes? • Think about what you would adjust or add in the receiver chain to make the radar ignore echoes that do not change in range or bearing over time. • Which options are more about frequency tuning and which are about comparing or filtering signals to detect motion?

✅ Before You Answer

• Identify which choice refers to using a special circuit to compare consecutive echoes and cancel those that remain constant. • Eliminate any options that only involve general calibration (tuning) rather than target discrimination. • Confirm which option implies using the discriminator in a way that distinguishes moving from non-moving returns.
