Abstract

A digitally modulated radar, DMR, transmitter module is disclosed comprising: a sequence generator, configured to generate a repeating digital sequence signal based on a relatively low-frequency clock signal; a mixer configured to combine the digital sequence signal with at least one phase-delayed copy of the digital sequence signal, to provide a combined signal; and a modulator configured to modulate a relatively high-frequency carrier signal, in dependence on the combined signal, to provide a modulated signal. Corresponding systems and methods are also disclosed.
