    摘要: A radar device transmits an electric wave whose band is spread by a PN code, receives a reflected wave of the electric wave from an object 10, detects correlation between a received signal and a PN code which is delayed, and thereby detects the object. A receiving part 18 connects three receiving antennas 16a.about.16c sequentially one by one, thereby to receive a reflected wave from an object. The three receiving antennas are arranged having their directions so staggered that their antenna beam patterns partly overlap with each other. A correlation detection circuit 19 detects such a slide width that a value of correlation between a received signal received by each of the antennas and the PN code exceeds a predetermined threshold. An operation part 12 obtains an azimuth of an object based on the detected slide width and beam pattern characteristics of the antennas.

    摘要: A radar device transmits by a transmitting part a wave whose band is spread by a PN code from a PN generator, receives at a receiving part a reflected wave from an object based on the wave and detects the object by detecting correlation between the received signal and the PN code. In this radar device, the received signal which is spread to a wide range is converted to a low-frequency band which is easy to be measured by a down converter so that a signal is generated when correlation is made by a delay of the PN code from a delay circuit, and generates a pulse signal through waveform shaping of the signal to detect the object and to measure its relative speed and distance at a processing part according to the pulse signal and the delay time.

    摘要: A high-precision distance measuring with a reduced error in a distance measuring system which calculates a distance from an arrival time of each pulse signal constituting a pulse sequence is provided. For an oscillator which generates pulse signals by counting the number of pulse signals constituting a received pulse sequence, a relative time difference between a transmitting device and a return device is acquired, a distance from the transmitting device to the return device is calculated, and the calculated distance is corrected based on the calculated relative time difference.
