A process and a device for detecting aircrafts circulating in an air space surrounding an airplane is disclosed. The device (1A) comprises means (2, 3) for detecting an aircraft circulating in the air space surrounding the airplane and, in case of a detection, for determining a first position and a second position of the aircraft with respect to the airplane, and means (8A) for comparing said first and second positions so as to check whether they match.

1. A process for detecting at least one aircraft (AI) circulating in the air space surrounding an airplane (AC), said airplane (AC) comprising a collision avoidance system (2) able to detect the presence of such an aircraft (AI), said process comprising the following steps: A/ monitoring said air space, by means of said collision avoidance system (2), so as to detect the presence of an aircraft (AI) and, in case of a detection, determining at least one first position (P) of said aircraft with respect to said airplane (AC);B/ monitoring said air space through the radar detection means (3) arranged on board said airplane (AC), so as to detect the presence of said aircraft (Al) and, in case of a detection, determining at least one second position (P2) of said aircraft with respect to said airplane (AC);Co/ determining a matching volume (V1, V2) centered around at least one of said first and second positions (P1, P2); andC/ when said collision avoidance system (2) and said radar detection means (3) each detect said aircraft (Al) in said air space, comparing said first position (P1) to said second position (P2), so as to check whether they match, using said determined matching volume (V1, V2). 2. The process according to claim 1, wherein, step C/ comprises: checking whether the other position (P1, P2) belongs to said matching volume (V1, V2); andin the case where the other position (P1, P2) belongs to said matching volume (V1, V2), it is considered that said first and second positions (P1, P2) match. 3. The process according to claim 2, wherein: said matching volume (V1, V2) has the form of a sphere with a predefined radius (R);the distance (d) separating said first position (P1) from said second position (P2) is calculated;said calculated separation distance (d) is compared to said predefined radius (R); andin the case where said separation distance (d) is at the most equal to said predefined radius (R), it is considered that said first and second positions (P1, P2) of said aircraft (AI) match. 4. The process according to claim 2, wherein said matching volume (V1, V2) has the form of a ring portion with a rectangular section. 5. The process according to claim 1, wherein step Co/ comprises: determining a matching volume (V1, V2) centered around each one of said first and second positions (P1, P2);checking whether there is at least one part common (C) to said thus determined matching volumes (V1, V2); andshould such a common part (C) exists, it is considered that said first and second positions (P1, P2) match. 6. The process according to claim 1, wherein, when said first and second positions (P1, P2) match, a consolidated position of said aircraft (AI) is determined with respect to said airplane (AC) from said positions (P1, P2). 7. The process according to claim 1, wherein: the detection radar means (3) are able to perform, through a wave beam (4), an azimuth scanning following a predefined aperture angle (5); andin step B/, by means of said wave beam (4), an azimuth scanning is performed according to several predetermined elevation angles (6), an elevation angle (6) being defined between the general direction of said wave beam (4) and an horizontal plane (7). 8. The process according to claim 1, wherein: said detection radar means (3) are able to perform, through a wave beam (4), an azimuth scanning following a predefined aperture angle (5);the step A/ is implemented preliminarily to step B/;after said aircraft (AI) has been detected by said collision avoidance system (2) in step A/, a monitoring area of said air space is determined around said first position (P1); andin step B/, a monitoring is performed of said determined monitoring area by means of said radar detection means (3). 9. A device for detecting at least one aircraft (AI) circulating in the air space surrounding an airplane (AC), said airplane (AC) comprising a collision avoidance system (2) able to detect the presence of such an aircraft (AI), said device being arranged on board said airplane (AC) and comprising:said collision avoidance system (2) able to monitor said air space, so as to detect the presence of an aircraft (AI) and to determine at least one first position (P1) of the latter with respect to said airplane (AC);radar detection means (3) able to monitor said air space, so as to detect the presence of said aircraft (AI) and to determine at least one second position (P2) of the latter with respect to said airplane (AC);means (9) for determining a matching volume (V1, V2) centered around at least one of said first and second positions (P1, P2); andmeans (8) for comparing said first position (P1) of said aircraft (AI) to said second position (P2), so as to check whether they match through said determined matching volume (V1, V2), when said collision avoidance system (2) and said radar detection means (3) each detect said aircraft (Al) in said air space. 10. An aircraft, comprising a device (1A, 1B) as specified in claim 9. 11. A process for detecting at least one aircraft (AI) circulating in the air space surrounding an airplane (AC), said airplane (AC) comprising a collision avoidance system (2) able to detect the presence of such an aircraft (AI), said process comprising the following steps: A/ monitoring said air space, by means of said collision avoidance system (2), so as to detect the presence of an aircraft (AI) and, in case of a detection, determining at least one first position (P) of said aircraft with respect to said airplane (AC);B/ monitoring said air space through the radar detection means (3) arranged on board said airplane (AC), so as to detect the presence of said aircraft (AI) and, in case of a detection, determining at least one second position (P2) of said aircraft with respect to said airplane (AC);Co/ determining a matching volume (V1, V2) centered around each one of said first and second positions (P1, P2);checking whether there is at least one part common (C) to said thus determined matching volumes (V1, V2); andshould such a common part (C) exists, it is considered that said first and second positions (P1, P2) match;C/ when said collision avoidance system (2) and said radar detection means (3) each detect said aircraft (AI) in said air space, comparing said first position (P1) to said second position (P2), so as to check whether they match, using said determined matching volume (V1, V2).
