Abstract: PURPOSE:To surely detect the frequency sweeping time when main sweeping or returning sweeping is performing on answering waves by adding a constant-current circuit to the saw tooth wave generating section of a sweeping signal generation circuit and linearizing the time-related charactermstics of the fallmng portions of saw tooth waves. CONSTITUTION:A sweeping signal generation circuit amplifies 10 and boosts 11 a pulse from a control section and sends saw tooth wave signals to a microwave oscillator after generating the signals by means of a saw tooth wave generating section 16. A constantcurrent circuit 17 for falling portions of saw tooth waves composed of a JFET 18 and variable resistor 19 is connected in parallel with a capacitor 14 to the output terminal of the section 16. When the JFET 18 is set to a pinched-off state by means of the resistor 19 when the means 16 generates the saw tooth wave signals, the current flowing between the drain and source becomes constant with respect to time and the discharge voltage of the capacitor 14 also changes at a fixed rate against time. Therefore, the occurrence of the omission of detection can be prevented, since the time-related characteristic of the falling portion of the saw tooth wave signals is linearized and the frequency sweeping time of answering waves from this radar transponder becomes longer.

Abstract: PURPOSE:To increase the value of mubeta and at the same time to ensure impression of the bias voltage suited to a VCO by setting an amplifier after an LPF and also setting optionally the action point of the amplifier. CONSTITUTION:A transistor TRQ serves as a circuit which produces the voltage VX and can be varied by a variable resistance R2. Here VO=-(RF/RX)VX+ (1+ RF/RX)v1 is satisfied between the output v1 of an LPF and the output VO of an amplifier 5. Then the control sensitivity beta of a VCO can be equivalently increased through amplification of the amplifier 5. In this case, the term (-RF/RX) VX functions to secure the coincidence between the bias voltage of the VCO and a center frequency. Thus it is possible to keep the oscillation frequency of the VCO at 4fSC by controlling the resistance R2 or by maintaining v1=0.
