RADAR HAVING PHASED ANTENNA ARRAY AND SYSTEM FOR TESTING CHANNELS THEREOF Russian patent published in 2015 - IPC G01S7/40 

FIELD: physics, navigation.

SUBSTANCE: invention relates to radar and can be used in multifunctional radar systems with an electronically controlled beam pattern. The radar comprises n emitters connected to n receiving-transmitting modules connected to each other. Each of the modules is connected to a power distribution device. All modules are connected to a control and primary signal processing unit. The input of the unit of the power distribution device is connected to a transmitter and a receiver, which are connected to the control and primary signal processing unit, having a reference generator. The radar also includes a portable antenna and three two-way microwave switches, the first of which is connected to the portable antenna and enables connection thereof to the second or third two-way microwave switch; the second two-way microwave switch is connected to the output of the transmitter and enables connection thereof to the first switch, and the third two-way microwave switch is connected to the receiver and enables connection thereof to the first switch, wherein the first, second and third two-way microwave switches are connected to the control and primary signal processing unit.

EFFECT: high accuracy of the radar.
