Abstract

In this paper, we derive closed expression of range-direction of arrival (R-DOA) information in phased-array radar. In our previous works, the theoretical expression of R-DOA information is proposed. Firstly, a uniform linear array system model is given, where R-DOA information is formulated as the mutual information between range, direction of arrival and the received signals with with complex additive white Gaussian noise. Then employing the a posteriori probability density function (PDF) of the range and direction of arrival to extract R-DOA information from echoes. Moreover, by dividing the integral region of the a posteriori PDF into the signal part and noise part, a closed approximate expression of R-DOA information is derived. Finally, numerical results are presented to verify the effectiveness of the proposed approximate closed expression.
