Abstract (en)
[origin: FR2862439A1] The antenna has two sub-antennas (2, 3), each with sensors (21-2M, 31-3N) to respectively form two line portions. Signal processing devices (6, 7) create useful signals by filtering noise from combined signals obtained from each portion. A calculation device (8) calculates correlation coefficients between the useful signals of the two portions, and creates a detection signal when a coefficient exceeds a preset threshold.
