Аnnotation: The problem of recovering ground displacement is incorrect, so additional assumptions are used to solve it, ensuring the stability of the resulting solution. An interactive correction of the trend in the time domain can be an alternative to the regularization of the solution in the deconvolution algorithm. It allows the group of long-period trends to be segregated in a seismic record without repeating the procedure. Interactive trend correction is applied within the proposed criterion. An algorithm is presented for calculating accelerograms from velocigrams with an integrated procedure for interactive correction of the long-period trend. The effectiveness of the algorithm, which is based on the relationship of the differential equation of motion of the pendulum with the true acceleration of the base of foundation is demonstrated experimentally.
