Title: Radar unit carried on vehicle
Inventor: YAMADA YUKINORI
IPC: G01S13/60
Filed: 1995-02-01
Abstract: PURPOSE: To obtain a radar unit in which the modulation frequency of carrier waves is changed on the basis of the relative distance of a computed target object, in which the relative velocity of a target object is detected with high accuracy at a short distance and in which the pairing operation of peaks in the frequency rise section and the fall section of a plurality of target objects is performed easily at a long distance. CONSTITUTION: A target recognition device 30 detects peaks of powere spectrums in a frequency rise section and a fall section so as to perform a pairing operation, and it finds a relative distance and a relative velocity simultaneously. A danger judgment device 32 compares magnitudes of a predetermined safe distance and the relative distance so as to judge a danger. Then, the resolution of a relative velocity obtained from a relative velocity frequency appearing as a frequency difference becomes large, the larger a modulation frequency is. When the modulation frequency is large, the relative velocity frequency becomes relatively smaller with reference to a relative distance frequency, and the measuring accuracy of the relative velocity becomes worse.  However, when a plurality of target objects exist, the difference between a peak in the frequency rise section and a peak in the fall section becomes smaller, and the pairing operation of the target objects can be performed easily.

Abstract: PURPOSE:To eliminate the need for any special operation for the reception of guidance and to eliminate noise by installing at least one set of information transmission equipment in a moving region of a guided person and allowing plural guided persons to carry a portable receiver respectively. CONSTITUTION:For example, information transmitters 1a, 1b,... are installed to the prescribed position of a route A of an exhibition.
