What is the purpose of clutter rejection in radar signal processing?

• A. To enhance signal strength
• B. To filter out noise and irrelevant signals
• C. To increase radar range
• D. To improve radar resolution

Answer: (B)

The purpose of clutter rejection in radar signal processing is primarily to filter out noise and irrelevant signals, making it essential for achieving accurate target detection. Clutter refers to unwanted echoes or signals that can obscure or distort the information of interest, often created by objects such as rainfall, terrain, or other environmental factors. By implementing clutter rejection techniques, the radar system can effectively distinguish between the actual targets and the extraneous signals that may interfere with target identification and tracking. This filtering process improves the clarity and quality of the radar signal, allowing operators to focus on desirable returns from actual targets while minimizing the impact of distracting noise. Therefore, filtering out noise and irrelevant signals is crucial for maintaining the integrity of the radar data and enabling effective decision-making based on the processed information.
