Amplitude weighting-based ground penetrating radar back projection imaging method

The invention discloses an amplitude weighting-based ground penetrating radar back projection imaging method, which belongs to the field of radar imaging. The traditional back projection imaging method has the problem of insufficient clutter and noise suppression ability. According to the amplitude weighting-based ground penetrating radar back projection imaging method, as for any imaging point A, time delay is used for calculating a scattering response amplitude xA,k=rk(t), and t=tauA,k of the imaging point in each channel; a response amplitude corresponding to a point on hyperbolic echo is acquired through edge extraction to form a window function; weighting is carried out on the scattering response amplitude xA,k of each channel, and imaging on the A point is completed through coherent superposition; and all imaging points are traversed to complete the entire imaging process. The window function is used for carrying out weighting processing on the scattering amplitude, the target detection precision is improved, and the noise and clutter interference suppression ability is improved.
