Embodiment Construction
[0060] According to the following Figure 1 to Figure 6 , the preferred embodiment of the present invention is described in detail.
[0061] like figure 1 As shown, the present invention provides a method for simulating echoes of electromagnetic pulse radars in coastal areas, comprising the following steps:
[0062] Step S1 , establishing a sea spectrum of the near-shore sea area.
[0063] The digital model generation of the sea spectrum of the coastal waters is based on the JONSWAP spectrum, and by introducing the shallowing coefficient To take into account the limited water depth in shallow water, it represents the wind and waves in the growth stage to a certain extent.
[0064] Based on the assumption that the energy flow is conserved as the wave propagates from one deep water location to the next finite water depth location, the water depth effect is linked to the sea spectrum by a shallowing factor.
[0065] The energy flow of a wave propagating from an infinite dept...
