Abstract
Satellite monitoring stations are often affected by strong clutter and interference when monitoring targets. When ground receivers receive target signals, they also receive noise, clutter, and interference signals. These signals have randomness and signal strength changes from time to time. Therefore, constant false alarm detection technology is used to detect interference signals. CFAR detectors construct different system functions in different clutter environments and maintain a constant false alarm rate by adaptively modifying the detection threshold. A comparison of CFAR algorithms shows that CA_ The CFAR algorithm has excellent monitoring performance in uniform environments_ CFAR is suitable for multi target environments, GO_ CFAR performs well in clutter edge environments, SO_ CFAR performs well under various conditions.
