The invention relates to an ice pool indirect measurement method for observing the waveform of an ice surface bending gravity wave, and the method comprises the following steps: carrying out the model test of an underwater navigation body at different navigation speeds according to the preset thickness of an ice cover and the immersion depth of the navigation body; a laser displacement sensor acquires vertical displacement time travel curves of the ice surface at the measuring point at different navigational speeds, and the maximum deformation amplitude of the ice surface at the measuring point is calculated; calculating a vertical displacement time travel curve of the ice surface at the measuring point under each working condition by utilizing a bending gravity wave theory; 5, calculating the maximum deformation amplitude of the theoretical ice surface; calculating the total difference between the maximum deformation amplitude of the test ice surface and the maximum deformation amplitude of the theoretical i
