High voltage line（HVL） is the main safety threat of low-flying aircrafts,and its accurate detectand effective early-warning is one of the most important functional requirements for low-altitude collisionavoidance radars at millimeter-wave（MMW）. This paper starts with introduction of the present research onHVL detection technology at millimeter-wave,then analyzes the main progress on electromagnetic scattering,detection algorithm and detection system of HVL detection,proposes that MMW collision avoidance radars should possess some necessary characteristics such as large scan volume,high data refreshment rate,high resolution,small target detection and anti-jamming clutter capability. Finally,it points out the maindeveloping trends of HVL detection technology,i. e. HVL detection algorithms based on multi-sensor information fusion,intelligence of active learning and depth information.
