Patent number: 9684062Abstract: A radar antenna device is provided for rotating an antenna unit which successively emits transmission signals. It is configured to reduce the capacity of an electric power source for supplying electric power to a transmission circuit, a drive unit and the like. A radar antenna device is comprised with an antenna unit and a control unit. The antenna unit is driven by a drive unit to rotate and emits successively transmission signals generated by a transmission circuit into an outer space. After electric power is supplied to the drive unit to be driven, the control unit controls the transmission circuit in response to the transmission start signal from the transmission start signal producer so that the electric power for the transmission will be supplied to the transmission circuit.Type: GrantFiled: October 14, 2014Date of Patent: June 20, 2017Assignee: FURUNO ELECTRIC COMPANY LIMITEDInventors: Yoshifumi Ohnishi, Suminori Ekuni, Motoji Kondo

Patent number: 7679548Abstract: A radar apparatus where the rate of writing detected image data into an image memory does not decrease, irrespective of an enlarged amount of the detected image data. When an azimuth direction enlargement section of a W data generator receives detected image data of a sweep, it outputs the data to an image memory, and delays the data, depending on a cycle of an azimuth direction shift timing signal. When detected image data of a next sweep is drawn into a pixel adjacent in a sweep moving direction to a pixel into which previous detected image data has been drawn and is located at the same distance in a sweep distance direction, the delayed data is compared with new data, and the greater data is drawn into the new pixel. When the delayed data is greater, this detected image data is enlarged in the azimuth direction.Type: GrantFiled: November 15, 2004Date of Patent: March 16, 2010Assignee: Furuno Electric Company LimitedInventors: Takumi Fujikawa, Motoji Kondo, Sae Takemoto

Publication number: 20070126624Abstract: A radar apparatus or like is provided in which a rate at which detected image data is written into an image memory is prevented from decreasing, irrespective of an enlarged amount of the detected image data. When an azimuth direction enlargement section 90a of a W data generator 9 receives detected image data of a certain sweep, the azimuth direction enlargement section 90a outputs the detected image data to an image memory 10, and delays the detected image data, depending on a cycle of an azimuth direction shift timing signal. Next, when detected image data of a next sweep is drawn into a pixel adjacent in an azimuth direction (sweep moving direction) to a pixel into which previous detected image data has been drawn and is located at the same distance in a sweep distance direction, the delayed detected image data is compared with new detected image data, and the greater data is drawn into the new pixel.Type: ApplicationFiled: November 15, 2004Publication date: June 7, 2007Inventors: Takumi Fujikawa, Motoji Kondo, Sae Takemoto

Patent number: 6441775Abstract: While received data is stored into a video memory through coordinate conversion, the level of image data is gradually reduced simultaneously with this, by which the image of a target is discriminately displayed readily from among a clutter even without performing adjustment which would conventionally be involved. The radar apparatus is composed of a video memory 6 for successively converting received data from polar to rectangular coordinates along with sweep rotation and storing the data, a FIRST detector for detecting a FIRST so that data write by the coordinate conversion is effected only at a time of FIRST detection, and a subtraction data generator 9 for subtracting a constant value from pixel data of a area designated by a subtraction area designator 14 on the video memory 6 during a period other than FIRSTs.Type: GrantFiled: May 2, 2001Date of Patent: August 27, 2002Assignee: Furuno Electric Co.

Patent number: 6424292Abstract: When the range scale has been changed, past target images which have been stored are converted to fit to a new range scale such that the past target images can be displayed in continuity on the new range scale without erasing the previously stored past target images. When the range scale is switched by operating a range selector 24, a controller 23 sets the amount of address shift K2 for a current-image video memory 20 and the amount of address shift K1 for a past-image video memory 21. Data in the past-image video memory 21 are successively read out according to K1 and transferred to the current-image video memory 20 in a first step. During this step, access address of the memory 20 is advanced according to K2. In a second step, the data stored in the current-image video memory 20 is re-transferred back to the past-image video memory 21 according to the re-set amounts of address shift K1 and K2.Type: GrantFiled: June 1, 2001Date of Patent: July 23, 2002Assignee: Furuno Electric Co., Ltd.Inventors: Takumi Fujikawa, Motoji Kondo
