    摘要: [Problem] To provide an information processing method, radar apparatus, and computer program which make it possible to recognize a false image on a radar echo. [Solution] Provided is an information processing method in which: image data that includes time-series radar images is acquired; position data of a first false image candidate is acquired by inputting one acquired radar image into a first training model that outputs the position data of the first false image candidate when one radar image has been inputted; position data of a second false image candidate is acquired by inputting the acquired time-series radar images into a second training model that outputs the position data of the second false image candidate when the time-series radar images have been inputted; and a false image on a radar echo is detected on the basis of the position data of the acquired first false image candidate and second false image candidate.

    摘要: An object is to enable measurement of position and velocity of a measurement object without the need for a complicated process such as a pairing process, without the need for a wideband signal that can be used only in a millimeter wave frequency band, and even when multiple measurement objects exist in a measurement region.
    A velocity measurement device includes a transmitting means, a receiving means, and a signal processing means. The transmitting means transmits a transmission signal by a transmitting antenna toward a measurement object. The receiving means receives a reflected wave from the measurement object with multiple receiving antennas and generates a reception signal for each of the receiving antennas. The signal processing means obtains a phase plane of the reflected wave with respect to an antenna plane of the multiple receiving antennas from a phase difference between the reception signals to specify an arrival direction of the reflected wave, obtains a distance to the measurement object from a propagation delay time of the reflected wave, and calculates a phase fluctuation of the reflected wave to calculate a velocity of the measurement object from the phase fluctuation.

    摘要: Analog video information from a radar antenna rotating once each 2 seconds and emitting 2000 pulses per second is digitized by an A/D converter (15) which feeds a sweep memory (16) comprising 1024 range cells each storing one pixel. The analog antenna bearing 0 is digitized by a synchro/digital converter (19) and its sine and cosine fetched from a ROM table and supplied to X and Y rate multipliers (18) whose other input is a constant frequency. The pixels in the sweep memory (16) are written to X and Y coordinate addresses, determined from their range and bearing coordinates by the rate multipliers, in an intermediate storage block memory (17). Of the 4.096.000 pixels per antenna rotation, a central processor unit (20), operating in accordance with an algorithm, writes only 1048576 final pixels, four at a time, to a radar display refresh memory (3, 21) from which these pixels, in cartesian coordinate format, are transferred in page mode through a line buffer (30) to a D/A video output unit (5) and thence to a monitor (4) which provides a raster scan display of 1024 x 1024 pixels corresponding to the PPI information produced by the antenna. In controlling the transfer of pixels from the block memory (17) to the radar display refresh memory (3, 21), the central processor unit (20) forms and uses a table of memory block addresses associated with 4096 possible antenna bearing values, each memory block occurring once only in the table.

    摘要: Radar display apparatus employs digital techniques to convert range/azimuth scan to T.V. scan. A digital store (17) contains data defining the brightness of levels for the picture cells of a T.V. display (30). The store (17) is continuously updated in accordance with received video from a digitiser (12). The correct cell in the store (17) for updating is identified by converting polar coordinates to Cartesian coordinates in a Sin ϑ, Cos generator (21) and integrators (22, 23). The contents of the store (17) for the addressed picture cell is modified by a control unit (16) in accordance with the digitised video return so as to represent the degree of positive correlation of returns in that cell on successive azimuth scans of the radar. Thus the brightness or colour of the cell on the T.V. display (30) represents this degree of correlation.
