The invention discloses a multi-
radar interference inhibition method for preventing interference in
digital radio frequency storing and forwarding. The method comprises the following steps: firstly, two pieces of
radar receiving
radar echo data; secondly, conducting interaction on the data of the radar to enable the data of the two pieces of radar to be synchronous; thirdly, aligning the integrated echo interference data of the two pieces of radar in sequence, and then performing interference cancellation
processing based on the minimum mean squared error, the least square or the like; fourthly, providing trace points exceeding a
detection threshold after the two pieces of radar conduct
pulse voltage matching and constant false-alarm rate (CFAR)
processing on the
radar interference echo data after interference cancellation of the data; and fifthly, fusing the trace points of the two pieces of radar, and providing a target track. According to the multi-
radar interference inhibition method, two radar platforms coordinate with each other through a network, and after received data of two pieces of radar is aligned sequentially, false interference of
digital radio frequency storing and forwarding received by radar main lobes is prevented by means of the
isotropy characteristics of
digital radio frequency storing and forwarding interference signals, the non-
isotropy characteristics of target echo signals as well as amplitude differences between signals and interference.
