Embodiment Construction
[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings.
[0021] Simulation method principle of the present invention is as follows:
[0022] Such as figure 1 Shown is the flow chart of the emulation of the dynamic sea surface laser pulse beam echo in the present invention, based on radiometrics, the pulse beam laser radar equation is established, the equation considers the scattering effect of sea water, and the surface element scattering model is characterized by the Torrance-Sparrow two-way reflection distribution function model; Based on the sea spectrum model and inverse FFT technology to complete the dynamic sea surface generation; use computer graphics technology to complete scene rendering, blanking, and clipping.
[0023] The specific steps of the simulation are as follows:
[0024] Step 1: Use an optical waveform measuring instrument to obtain the discrete data of the spatial intensity distributio...
