MULTI-POSITION SURVEILLANCE SYSTEM Russian patent published in 2022 - IPC H04B7/26 G01S13/52 

FIELD: aircraft flight control.

SUBSTANCE: invention relates to the field of flight control of aircraft and can be applied in multi-position airspace surveillance systems used to control aircraft flights on the route and in the area of airfields. Each of the N identical receiving sensors MPSS additionally contains a frequency separation device (FSD), a television signal receiver (TSR), an additional ADC, a control strobe driver and a switch. The input of the CRU is connected to the output of the receiving antenna and consists of the combined inputs of a high-pass filter (HPF) and a low-pass filter (LPF) connected in parallel. The output of the HPF is connected to the input of the receiver and is the first output of the FSD. The TSR receiver input is connected to the low-pass filter output, which is the second output of the FSD. The signal input of the additional ADC is connected to the output of the TSR receiver. The clock input of the additional ADC and the input of the control strobe shaper are connected to the output of the local clock. The first (signal) input of the switch is connected to the ADC output, the second (signal) input - to the output of the additional ADC, the third (control) input - to the output of the control strobe shaper, and the output is the sensor output.

EFFECT: improving the accuracy and reliability of the multi-position surveillance system (MPSS).
