The invention relates to a uniformed
linear array beam forming method based on time reversal, belongs to the time reversal target directional technology of
shallow sea multi-path channels, and relates to the field of time reversal and array
signal processing. The uniformed
linear array beam forming method based on the time reversal resolves the problem of uniform linear target direction under a strong
noise interruption background. Due to the fact that the time reversal is capable of conducting cophasal stacking of multi-path signals based on
transmission channel matching, energy for receiving signals is reinforced, consequently
system gain of
signal detection is improved, and therefore the time reversal has strong advantages of
signal detection under a strong
noise circumference, particularly under the background of
shallow sea multi-path channels. Meanwhile, the application of the time reversal in the target direction field is perfected by self-
adaptation beam forming of the uniform
linear array,
beam control can be conducted conveniently by the acquirement of an optimal weighting factor of each
array element by using the uniform linear array under the target direction background, spatial filtering is conducted to a self-
adaptation beam forming directional diagram, and thus purpose of precise orientation is achieved.
