Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings.
[0032] Refer to attached figure 1 , the concrete steps of the present invention are described as follows:
[0033] Step 1. Construct the steering vector in the interference airspace.
[0034] Substitute the azimuth angle of the opponent's interference source into the interference steering vector formula to obtain the interference airspace steering vector.
[0035] The described interference steering vector formula is as follows:
[0036]
[0037] Among them, a(θ k ) represents the azimuth angle θ of the opponent’s kth interference source k The steering vector in the interference space at , the value range of k is [1,K], K represents the total number of interference sources, exp represents the exponential operation with a natural constant as the base, j represents the symbol of the imaginary unit, π represents the pi, · represents the phase Multiplication operat...
