  • Conventional direction finding algorithms for wideband signal need to preliminarily estimate the Direction of Arrival (DOA) and power of the noise roughly, and it has large focusing error. In order to solve these problems, a super-resolution direction finding algorithm for two dimensional (2-D) wideband chirp signals is proposed, the Fractional Fourier Transform (FRFT) is applied to focus the energy of the signals in every frequency by the rotational characteristic of FRFT, then algorithm for… CONTINUE READING
