Embodiment Construction
[0047] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0048] refer to Figure 1 ~ Figure 2 As shown, the target detection method based on adaptive frequency-domain non-coherent accumulation described in the embodiment of the present invention includes the following steps:
[0049] (1) two threshold values T11=16dB, T12=12dB of setting first level threshold, two threshold values T21=16dB, T22=13dB of setting second level threshold, initialization second level threshold T2= 0;
[0050] (2) Calculate the frequency domain data of the input signal, as follows:
[0051] For an input signal x(n) of N points (N is an integer power of 2) in a frame, N point data X(k) is obtained after FFT transformation:
[0052] X ( k ) = Σ n = 0 N ...
