Embodiment Construction
[0040] Below in conjunction with formula and accompanying drawing, method of the present invention is described further:
[0041] Such as figure 1 As shown, the first-order echo spectrum extraction method under the strong interference environment using the multi-domain information of high-frequency ground wave radar mainly includes constructing the multi-domain spectrum and formulating constraints, enhancing the power of the first-order echo spectrum, and searching for the maximum SINR The way to extract the first-order echo spectrum, the specific steps are as follows:
[0042] Step 1: The utilization period is T seconds (attached Figure 4 , 5 In 300s as an example), the ground wave radar multi-channel down-converted signal is processed by matched filtering and coherent accumulation, and the multi-channel range-Doppler spectrum is weighted in space and takes the maximum value in each direction to form Range domain-Doppler-azimuth spectrum, denoted as s(r,f,θ), its physical...
