摘要:
A vehicle detection device includes: a first signal obtaining section which obtains a first signal corresponding to a distance to a subject object; a second signal obtaining section which obtains a second signal corresponding to a solid angle formed by the subject object; and a vehicle determining section which determines, based on the first and second signals, that the subject object is a vehicle, in a case where an actual size of the subject object is equal to or greater than a predetermined size.
摘要:
A vehicle detecting sensor assembly (1) includes a microwave module (4) and a radome (5) for detecting the presence or absence of a parked vehicle, parked in a predetermined parking area (3), according an FMCW scheme. A shielding member (10) is provided on each of left and right sides, each of upper and lower sides or each of upper and lower and left and right sides of the module so as to protrude in a direction, conforming to the direction of transmission of a microwave, so that a detection range angle by the microwave can be varied in dependence on the position of the sensor and the size of the parking area, and a so disposed that the distance of separation between the module and the radome, through which the microwave passes, may lie in the vicinity of n times the half-wave length of the microwave.
