Abstract

Two structural diagrams for the designing of landing radars are compared. The first diagram of radar construction is based on the use of a single receiving-transmitting phased array antenna that forms a scanning four-beam directional pattern in receive mode and narrow probing beam in transmission mode. The second diagram is the radar with separated receiving and transmitting antenna systems. The phased array antenna is also used as the receiving antenna system. A separate transmitting antenna system consists of a set of separate radiating units, each of which sequentially irradiates its section of the radar coverage area by switching of the transmitter to a choosing unit. The process of searching of an aircraft and measuring its angular coordinates, range and speed in a particular area section of the radar coverage is synchronized with the switching of the microwave probing transmitter signal to the unit wich irradiates this section.
