Abstract

Multipath effection seriously affect the low elevation Angle estimation in MIMO radar,This paper Establish the multipath signal model , and put forward a kind of secondary general MUSIC algorithm based on unitary transformation (DU-G_MUSIC). First Based on general MUSIC algorithm, a joint estimation algorithm of elevation angle and multipath fading coefficient about target is proposed , In order to reduce the computational complexity, Avoiding search a wide range of angles, Then use the characteristics of the unitary transformation matrix, structure of real number domain data, get the initial estimation of low elevation Angle, And on the basis of initial estimates to obtain the real value of multipath fading coefficient, finally the DU-G_MUSIC algorithm on the real number field is used to estimate the optimized low elevation values. Due to multipath fading coefficient combined with Angle estimation, greatly improve the efficiency of the operation, to avoid the tedious decorrelation smoothing procedure, get high Angle resolution, on the premise of no loss of array aperture, reduces to the special requirements of array structure, has high engineering value.
