For the problem of beam distortion and detection blind zone by time domain interferences suppression method

a modified interferences suppression method by the energy compensation in time domain is proposed.Firstly

constructs energy compensation factor according to the frequency band of processing data and attenuation curve.Then

preprocesses the received data via time domain interferences suppression method

and obtains the output beam.Lastly

utilizes the energy compensation factor improve the output beam

reduces the beam distortion and detection blind zone

and achieves the expected results of interferences suppression and detection.The numerical simulation and data processing results show that

this method improves the time domain interferences suppression method by constructing energy compensation factor

reduces the impact of the wide concave or convex beam of time domain interferences suppression method on detecting target

achieves the beam correction

reduces detection blind zone

and achieves detecting the targets in old attenuation interval.That fundamentally solves the problem of beam distortion and detection blind zone by time domain interferences suppression method.
