Analysis of Space Probe Performance of Different Array Manifold Spectrum Estimation

摘要：

　　Different kinds of spectrum estimation algorithm based on the Uniform Linear Array (ULA) may not be directly applied to the Uniform Circular Array (UCA), due to the complexity of the expression which describes the UCA manifold.The UCA occupies a huge area, so in practice where space is limited, the direct of arrival (DOA) may not be properly estimated.On the basis of the above, an Lshaped array of 9-elements is proposed to satisfy the requirement of the space probe.Its calculation is simplified, and the error of the angle estimation is reduced.Thus, in the same simulation condition, the performance of the L-shaped array is better than that of the UCA, and the L-shaped array have been successfully applied in the non-cooperative target detection.
