[0065] 1) Estimation of interference subspace based on MPASTd
[0066] Assuming that the uniform linear array is composed of N array elements, and the antennas of each array element are isotropic, the signal model of its detection unit can be expressed as follows:
[0067] z = a u b+n (1) In the formula, z represents the output signal of the detection unit array, b represents the complex envelope of the target, u represents the direction parameter and u=sinθ, θ is the azimuth angle of the target, Superscript T Represents the transposed symbol, λ is the wavelength of the transmitted signal, d is the distance between array elements, and n represents interference plus noise. Assume that the interference plus noise obeys a Gaussian distribution with a mean value of 0 and a covariance of Q, and the interference, noise and target are not correlated with each other.
[0068] The MPASTd algorithm is improved on the basis of PASTd. For radar application scenarios, first use the sa...
