摘要： A monopulse radar system aims to correct an amplitude error and a phase error developed between receiving channels and improve the accuracy of a detected angle. To achieve the above aim, part of a transmit signal is supplied to respective channels on the receiving side through a signal transmission line for calibration. At this time, the gains of a variable phase shifter and a variable gain amplifier are adjusted so that an azimuth angle of a pseudo target, based on a signal for calibration, which is calculated by signal processing means, reaches a predetermined angle. Therefore, calibration work is simplified and an angular correction can be automated. Therefore, the present monopulse radar system is capable of coping even with variations in characteristic after product shipment due to environmental variations and time variations in parts characteristic.

摘要： The oscillator includes an active device, a substrate, a microstrip line formed on the substrate, and a dielectric block. The resonator is made up with the microstrip line and the dielectric block that is disposed so as to couple with the microstrip line. The active device produces a negative resistance in a desired oscillation frequency band. The dielectric block is set such that a resonance frequency of the lowest order mode of the dielectric block is lower than a desired oscillation frequency, and the resonance frequency of one of the higher order modes coincides with the desired oscillation frequency. The oscillator is generated with the higher order mode of the resonator. Thus, the invention provides at a low cost a millimeter wave band oscillator of a low phase noise by using this oscillator, and a transmitter-receiver module and a radar system applying this oscillator to the local signal generator.

摘要： There is provided a highly accurate velocity sensor having a reduced detection error. A sensor circuit unit generates an electromagnetic wave and emits it from a transmission antenna. Furthermore, a reception antenna receives a reflection wave from the ground and a mixer mixes it with a local signal, thereby generating a low-frequency signal. The electromagnetic wave emitted from the sensor circuit unit shapes a beam by a dielectric lens before emitting it toward the ground. Here, the beam shape is such that the beam width in the vicinity of the sensor is smaller than the beam width in the vicinity of the ground.

摘要： There is provided a radar system for improving distance resolution while preventing generation of ghost by an object located in the outside of the effective distance for detection. In this radar system, the signal generated by a voltage-controlled oscillator is transmitted only for the predetermined period by turning ON a switch only for the predetermined time length t1 with an interval of the predetermined period t2. Moreover, the time for detecting the receiving signal is limited to the predetermined period t3 (=t1) from the timing of transmission of the transmitting signal and the reflection signal from the object located in the outside of the effective distance is eliminated by limiting a local signal inputted to a mixer to the period t1.

摘要： A transfer impedance from input terminals of a resonator to output terminals of the resonator is larger than a driving-point impedance of the input terminals of the resonator at an oscillation frequency. The input terminals of the resonator are connected with the drain terminals of transistors Q1 and Q2 that are outputs of a differential amplifier, and the output terminals of the resonator are connected with gate terminals of the transistors Q1 and Q2 that are inputs of the differential amplifier. With this configuration, during the oscillating operation, the oscillation voltage amplitude of the gate terminals of the transistors Q1 and Q2 becomes larger than the oscillation voltage amplitude of the drain terminals. Therefore, it is possible to prevent the transistor, which is oscillating, from operating in a triode region, and suppress the deterioration of the Q-factor.
