Title: Fm radio altimeter
Inventor: FUNADA TAKAYOSHI
IPC: G01S13/34
Filed: 1994-02-01
Abstract: PURPOSE:To combine a cable and an antenna by providing a low-pass filter outputting a beat signal from which the transmission signal on the input side of a counter circuit is removed, and connecting the joint of an antenna and a diode for mixer through a high frequency cable with the joint of an FM oscillator and the low-pass filter. CONSTITUTION:A high frequency wave, subjected to FM modulation with a triangular wave from a triangular oscillator 1, is outputted from an FM oscillator 2. It is then radiated from an antenna 13 and at the same time applied to a diode 14 for mixer. The diode 14 constitutes a circuit for all-owing conversion of receiving frequency connected at the feeding point of the antenna 13. Consequently, a receiving signal is mixed with a receiving signal to produce a beat signal which is fed to a transmitter/receiver 10. After the transmission signal is separated from the beat signal through a low-pass filter 15, the beat signal, is amplified through a video amplifier 7 and converted through a counter circuit 8 into an altitude signal which is presented on a display section 9. Since a mixer is constituted in the antenna, a signal high frequency cable 12 can be used for transmission and receiving.

Abstract: PURPOSE:To omit a power supply exclusive for diode OR output of a control circuit, etc., and to reduce the cost of the power supply, by providing a power supply monitoring circuit which monitors the power supply voltage of another system and delivers a cut-off signal for power supply of another system when said power supply voltage is lower than a fixed level, an FF, etc. CONSTITUTION:When a system 9 is included in a working system, the Q output of an FF 1 is supplied to the reset input of an FF 13 via interfaces 12 and 24, an AND gate 18 and an OR gate 20. The Q output of the FF 13 is equal to zero and a system 21 receives an instruction to serve as standby system. When a power supply 28 is switched off, the power supply voltage in a power supply monitoring circuit 4 is lowered less than a fixed level. Thus the circuit 4 outputs an another system power supply cut-off PDWN signal to set the FF 1 and to define the system 9 as the working system. Furthermore a gate 6 is inhibited so that the system constitution instruction signal of the FF 13 is neglected and the Q output of the FF 1 is fixed at one. When a power supply 27 is switched off, the PDWN signal is outputted from a power supply monitoring circuit 16 and a working system is indicated to the system 21 via the FF 13 In such a constitution, the structure of a duplex system is simplified together with reduction of the cost.
