Power transmission line detection using an azimuth angular profile matching scheme

This paper presents high-voltage power transmission line detection with millimeter-wave (MMW) radar for the purpose of helicopter collision avoidance. In order to improve the detection, an azimuth angular profile matching (APM) scheme of the power transmission line based on the Bragg scattering phenomenon is suggested. For the evaluation of detection, we carried out a Monte Carlo simulation both at 94 GHz and 35 GHz, where a white Gaussian noise is considered as an additive noise. The results show that the detection probability with the APM at 94 GHz is much higher than that at 35 GHz and the detection performance is much improved by employing the APM
