摘要： A pulse signal is produced in a pulse generating section, and repetitively transmitted from an antenna at constant time intervals. A reception signal, received through an antenna and including a reflective wave from an object, is amplified and gain-adjusted. Thereafter, a distance detecting section detects a reception pulse of the reflected wave, and calculates the distance to the object. The variable attenuator attenuates the reception signal by a gain adjusted in accordance with a gain control signal. The gain of the variable attenuator is controlled so as to be maximum immediately after the pulse signal is transmitted, and to be reduced with elapse of time. Based on a gain adjustment timing signal, a gain adjustment timing when the attenuation amount is changed is made different for each transmission of the pulse signal.

摘要： A first radar transmitter and a second radar transmitter transmit a first modulation signal and a second modulation signal which are generated by repeating a predetermined time of code sequences, each of which has a predetermined code length, using a first code width and a second code width, respectively. An A/D converter converts the modulation signal into a discrete signal in a sampling cycle shorter than a difference between the first code width and the second code width. A positioning section separates a plurality of reception signals using a first correlation value based on outputs from the A/D converter and a first delay section corresponding to the first code width and a second correlation value based on outputs from the A/D converter and a second delay section corresponding to the second code width.

摘要： The disclosed technique includes transmitting a signal intermittently according to a transmission cycle having a predetermined transmission period and a non-transmission period; receiving the signal reflected from a target with reception antennas; and detecting the target from the reflected signal. A high-frequency transmission signal attenuated during the transmission period and a receipt signal received during the non-transmission period are combined together. A correlation value between a reference transmission signal and the receipt signal in the combined signal is calculated, and the amount of phase shift in an arbitrarily selected reception antenna is calculated from the correlation value of a reference reception antenna, and the correlation values of the other reception antennas. The phase component of the correlation value of the arbitrarily selected reception antenna is corrected on the basis of the amount of phase shift.

摘要： Under control of a first transmission code controlling section, a first radar transmitting section periodically transmits a first radar transmission signal with a first transmission period based on a first transmission trigger signal produced after elapse of a first delay time period from reception of a predetermined synchronization establishment signal by a first transmission trigger signal producing section. Under control of a second transmission code controlling section, a second radar transmitting section periodically transmits a second radar transmission signal with a second transmission period similarly. In accordance with the first delay time period and the second delay time period, arrival times of interference signals from the first radar transmitting section and the second radar transmitting section are within transmission zones of the second radar transmission signal and the first radar transmission signal.
