Optimization of Direct Direction Finding Method with Two-Dimensional Correlative Processing of Spatial Signal

Tsyporenko V. V., Tsyporenko V. G.

nr 4

46--53

In this article, the main parameter of the correlative-interferometric direction ﬁnding method with twodimensional correlative processing of spatial signal in the aperture of a linear antenna array (AA) is determined as the value of spatial shift within the AA aperture. The corresponding objective function is also formed. Analytical optimization of this parameter is presented and a comparative analysis of analytical calculations based on simulation results is conducted. In the simulation, a range of dependencies of the middle square deviation of estimation of direction on the value of the spatial shift for a signal-to-noise ratio of 0 dB, for minimum 3-sample and 4-sample Blackman-Harris windows of the spectral analysis, is received. The value of the middle square deviation of estimation of direction will be minimal and will equal 0.02 degrees using a minimum 3-sample Blackman-Harris window with the −67 dB level of side lobes. It oﬀers high noise immunity and high accuracy of direction ﬁnding.
