Present radar systems cannot assign radial velocities to targets which are clustered in the range-Doppler plane. This article describes a range-dependent multiplexed pulse for a radar to transmit and how to process the echo created by such a pulse when it is reflected by a cluster in the range-Doppler plane. The range-dependent multiplexed transmitted pulse is described as follows: (Image Omitted) Next, compute the Fourier transform of E(t). It can be shown to be of the form where U denotes the Fourier transform of U. Since we assume that the targets are clustered in the range-Doppler plane, the yj are clustered and the fk are very far apart. Furthermore, the signal is constructed so that U is narrow banded.
