摘要： PROBLEM TO BE SOLVED: To suppress transmission of unwanted radio waves, and to detect a preceding vehicle, even when the user's vehicle is stationary. SOLUTION: This radar system which is being carried on the vehicle and scanning a prescribed scanning range with a radar wave includes a transmission control means, which transmits the radar wave at each first unit angle within the above scanning range, when a running speed of the vehicle is a first speed and transmits radar waves at each second unit angle which is larger than the first unit angle within the scanning range, when the running speed is a second speed slower than the first; and since a target object detecting means which detects the target object, based on the reflected waves from the target object of the transmitted radar waves, the radar system as a whole can suppress the transmission of an unwanted radar waves, while regarding the target object located at a short distance, the system can obtain the point of reflection of the radar waves which are required for detecting the object.

摘要： PROBLEM TO BE SOLVED: To surely discriminate a plurality of targets by a radar device.
SOLUTION: Transmission signals having three or more kinds of frequencies are outputted from an oscillator 10, and transmission waves are radiated from a transmitting antenna 14 toward a target 100. Reflected waves are received by a receiving antenna 16, and the transmission signal is mixed with a receiving signal by a mixer to generate a beat signal. A signal processing device 24 detects a Doppler frequency signal from the beat signal by FFT and detects a distance to the target 100 by Fourier analysis, by using a complex signal component of the Doppler frequency signal in each channel as a progression. The maximum detection distance is increased by differentiating a frequency difference between the three or more kinds of transmission signals.

摘要： PROBLEM TO BE SOLVED: To prevent reduction of cooling efficiency of an on-vehicle radar apparatus even when the scanning angle range during low-speed running is widened. SOLUTION: The vehicle radar apparatus includes: a radar transmission/receiving device for transmitting and receiving a radar signal at each unit angle in a predetermined scanning angle range; and a target object detection means for detecting a target object based on a radar signal transmitted and received at each first unit angle in a first scanning angle range when the vehicle is running at a first speed, and detecting the target object based on a radar signal transmitted and received at each second unit angle, which is wider than the first unit angle, in a second scanning angle range, which is wider than the first scanning angle range, when the vehicle is running at a second speed which is slower than the first speed. The vehicle radar apparatus prevents temperature rise of the signal processing device because the amount of signal processing is low even when a wider range is scanned during low-speed running.
