Abstract:

The detection of radar signal always processes with background noise,not only high signal noise ratio but also constant false alarm device are required to reduce constant false alarm.Constant false alarm processing is an important part of radar signal processing;therefore the research on false alarm processing is crucial in radar technology.Slow-threshold constant false alarm aim at the heat noise of receiver,a constant false alarm processing circuit based on FPGA embedded design is proposed in this paper,and the simulation model and simulating results are also presented.The circuit has been used in a practical detector with big economic benefit.

Key words: slow-threshold;constant false alarm processing;FPGA
