Description

technical field

[0001] The present invention relates to a dual-frequency transmission mode in the field of radar overall design and signal processing and a clutter suppression method based on dual-frequency real-time processing, in particular to a method for improving clutter suppression capability, which can be widely used in pulse radar systems designing. Background technique

[0002] The clutter environment is caused by a large number of scattering units (such as terrain, ground objects, ocean waves) distributed on the surface of the earth or scattered in a certain volume of space (such as meteorological reflections and metal chaff). Taking effective measures will seriously affect the low-altitude detection performance of ground radar. The clutter suppression ability refers to the ability of the radar to suppress the interference clutter from the ground, sea surface, air and other areas during the detection process. It is an important indicator for evaluating the perform...
