Enhanced vision system for an aircraft , comprising: - at least a vision sensor of a ground in an observation direction (D), the ground being located in front of and below the aircraft ; - a processing unit able to form a reflectivity map of the ground from data collected by the vision sensor; - a display of ground images reconstituted by the processing unit from the reflectivity map and/or of information characteristic of the ground, created by the processing unit from the reflectivity map, the display being intended to be placed in a cockpit of the aircraft ; wherein the vision sensor is an electromagnetic sensor comprising a plurality of transmitters of a transmitted signal, the transmitters forming at least one group of transmitters , and a plurality of receivers of a received signal, resulting from the transmitted signal following reflection off of the ground, the receivers forming at least one group of receivers , the electromagnetic sensor including a waveform generation assembly powering each transmitter in order to generate the transmitted signal and a assembly to capture the signal received by each receiver after reflection off of the ground, the transmitters being distinct and spaced apart from the receivers , being arranged so as to form, from each combination of a transmitter and of a receiver , between the group of transmitters and the group of receivers , at least one virtual transmitters/receivers network extending along an elongation direction (A) perpendicular to the observation direction (D), the linear density of virtual transmitters/receivers in the network along the elongation direction (A) being greater than the linear density of transmitters in the group of transmitters along the elongation direction (A) and being greater than the linear density of receivers in the group of receivers along the elongation direction (A), characterised in that at least one group of transmitters intended to be placed on one of an upper surface or a lower surface of a skin of a substantially frustoconical intermediate area of a front tip of the aircraft and at least one group of receivers to be placed on the other of the upper surface or the lower surface of the skin of the substantially frustoconical intermediate area . - at least a vision sensor of a ground in an observation direction (D), the ground being located in front of and below the aircraft ; - a processing unit able to form a reflectivity map of the ground from data collected by the vision sensor; - a display of ground images reconstituted by the processing unit from the reflectivity map and/or of information characteristic of the ground, created by the processing unit from the reflectivity map, the display being intended to be placed in a cockpit of the aircraft ; the transmitters being distinct and spaced apart from the receivers , being arranged so as to form, from each combination of a transmitter and of a receiver , between the group of transmitters and the group of receivers , at least one virtual transmitters/receivers network extending along an elongation direction (A) perpendicular to the observation direction (D), the linear density of virtual transmitters/receivers in the network along the elongation direction (A) being greater than the linear density of transmitters in the group of transmitters along the elongation direction (A) and being greater than the linear density of receivers in the group of receivers along the elongation direction (A), characterised in that at least one group of transmitters intended to be placed on one of an upper surface or a lower surface of a skin of a substantially frustoconical intermediate area of a front tip of the aircraft and at least one group of receivers to be placed on the other of the upper surface or the lower surface of the skin of the substantially frustoconical intermediate area . <EOS>
