IPC: G01S19/25
Filed: 1988-05-13
Abstract: PURPOSE: To minimize the influence of the failure of a switch on a power splitter and, at the same time, to continuously operate the splitter even when the switch becomes faulty by constituting two signal sources so that the sources can be switched to each other through the combination of the power splitter and switch. CONSTITUTION: Signal sources 10 and 20 respectively give their signals to power splitters 40 and 70 through lines 30 and 60 and, after distributing the signals to outputs 51-54 and 81-84, give the signals to an switch array 90. The array 90 is composed of single-pole double throw switches 100 and the position of each switch is controlled by a main beam steering unit(BSU) 130 or a standby BSU 140. When a failure is detected in the signal source 10 while all switched 100 are at upper positions and each input 101 is connected to a switch output 103, a BSU 150 actuates the switches 100 and moves the switches 100 to lower positions so that the inputs 102 can be connected to switch outputs 103. Since the signal source 20 gives necessary power to a landing system through the splitter 70, the landing system does not become inoperative even when one of the switches 100 becomes faulty.
