摘要： PURPOSE:To detect the presence of an electromagnetic wave such as an X band radar signal or K band radar signal by inserting a key signal like a pilot signal to an antenna output, and using only a signal including the key signal as the detecting signal. CONSTITUTION:A signal of the X band antenna 10 is coupled to a mixer 14 and heterodyned with a signal from a local oscillator 16 and frequency-modulated by the pilot signal. The output of the mixer 14 is fed to a common amplifier 20 via an IF amplifier 18. A K band antenna 12, mixer 22, local oscillator 24, and an IF amplifier 26 are constituted similarly. The output of the common amplifier 20 is connected to a mixer 28 receiving a signal from a local oscillator 36. The output of a band pass filter 34 is amplified by a tuning amplifier 36 and fed to a discriminator 38. The intermittent pilot signal demodulated by the discriminator 38 passes through a narrow band pass filter 40 and is given to a PLL42 via the amplifier 41.

摘要： PURPOSE:To display the receiving band by driving such as a buzzer driving circuit in receiving at an X band and a K band, respectively. CONSTITUTION:An X band antenna 10 is coupled to a mixer 14 and an output from the mixer 14 is connected to an IF amplifier 18. The output of a K band antenna 12 is connected similarly to a mixer 22 and an IF amplifier 18. An output of a common amplifier 20 is connected to the 2nd mixer 28. The frequency of the 2nd local oscillator 30 is swept. A discriminator 38 detects an intermittent pilot signal, which passes through a BPF 40-1 and is given to a PLL 42-1. The phase of this signal is compared with the continuous VCO output fed from a VCO 44-1 at a phase comparator 46-1. The result of comparison operates a switch 56-1 to make a buzzer driving circuit 58-1 and a lamp driving circuit 60-1 operate.

摘要： PURPOSE: To improve the receiving performance by providing a conductive metallic body to a diagonal position of the inside of a horn from a throat to an aperture.
CONSTITUTION: A conductive member 18 is placed nearly at any of two diagonal lines of the aperture 16 of a horn antenna 12. The member 18 should not be placed on both the diagonal lines but provided to one of the two diagnoal lines without fail. Remarkable improvement of the antenna receiving sensitivity is recognized by providing the member 18. Moreover, the difference of sensitivity due to horizontal and vertical polarized waves is avoided. Thus, excellent receiving is attained even if the horn antenna is installed on any angular position.

摘要： PURPOSE:To obtain a wide PLL frequency range with detuning reduced, by controlling a voltage-controlled oscillator VCO by a voltage regarding an output frequency setting digital data supplied to a programmable frequency divider. CONSTITUTION:A digital frequency-division indication signal P supplied to a programmable frequency divider 12 is supplied to a D/A converter 22 as well. The output Vo of the converter 22 has a voltage value corresponding to the specified frequency-division ratio N of the frequency divider 12, and a VCO10 is controlled by the voltage. The VCO10 has an oscillation frequency specified by the Vo, and the frequency is divided by N at the frequency divider 12, whose output is compared, in terms of phase, with a reference signal from a reference frequency generator 14 by a phase comparator 16 to supply their difference to the VCO10 as a voltage Vp through an LPF18. The principal decision on a PLL output frequency by the signal P is made by the output Vo of the converter 22 and only the correction for accurate PLL output setting is performed by the output Vp of the LPF18, so the modulation sensitivity of VCO is set small, thereby reducing noises in the PLL output signal following up large modulation sensitivity.
摘要翻译：目的：通过控制压控振荡器VCO，通过将输出频率设置为提供给可编程分频器的数字数据的电压来获得具有失调的宽PLL频率范围。构成：提供给可编程分频器12的数字分频指示信号P也被提供给D / A转换器22。转换器22的输出Vo具有与分频器12的指定分频比N相对应的电压值，VCO10由电压控制。 VCO10具有由Vo指定的振荡频率，并且在分频器12处将频率除以N，其相位与相位比较器16的参考频率发生器14的参考信号相比较，通过LPF18将其与VCO10的差值提供为电压Vp。通过信号P的PLL输出频率的主要决定由转换器22的输出Vo进行，并且仅通过LPF18的输出Vp执行用于精确PLL输出设置的校正，因此VCO的调制灵敏度被设置为小，从而降低PLL输出信号跟随大调制灵敏度的噪声。
