Abstract
The invention relates to a surface wave radar system comprising a first array (RT) of emitting elements (Tx) configured to emit surface wave signals at a wavelength λ, a second array (RR) of receiving elements (Rx) configured to receive the signals after they have been reflected by targets, a power supply unit for the system, and a processing unit (ECU) for processing the reflected signals, characterized in that: - the first array (RT) of emitting elements (Tx) comprises a plurality of at least two identical sub-arrays (SRT) of linear emitting elements (Tx) each extending in a first direction (DT) over a length (LSRT), - the second array (RR) of receiving elements (Rx) is an array that is also linear and extends in a second direction (DR) perpendicular to the first direction (DT). The invention also relates to the use of such a system for detecting and tracking maritime targets.
