专利汇可以提供Aircraft contained perspective radar/display and guidance for approach and landing专利检索,专利查询,专利分析的服务。并且A radar system is disclosed as for providing the pilot of an aircraft with a perspective presentation that is sufficient, for example to land the aircraft under conditions of reduced visibility including zero-zero. The system incorporates a cathode ray tube utilizing B-scope scanning with a somewhat hyperbolic vertical range sweep which may be further varied as a function of the profile of the terrain under investigation where the terrain is not reasonably flat (perpendicular to the local vertical). The sweep signal is developed in a somewhat-basic, synthetic form, for depicting large flat areas (as generally presented by airports). Means are also disclosed for varying the standard in accordance with altitude. A form of the system is also disclosed to vary the display in accordance with roll and pitch of the aircraft. Furthermore, various registration systems are disclosed whereby the perspective display is registered or referenced with regard to the terrain under investigation, as to indicate when the terrain is irregular. Some forms of registration incorporate structure for obtaining accurate visual display of actual irregular terrain. Also means is disclosed for determining (by means of the radar/display) if the aircraft is above or below the predetermined glide slope angle with respect to the local vertical and the end of the runway or landing zone.,下面是Aircraft contained perspective radar/display and guidance for approach and landing专利的具体信息内容。
