A computer graphics display system and method which places moving and color changing geometric shapes, which represent tasks of a project, on a circular graph by means of a display such as a computer monitor, (similar to a radar screen) which alerts the user to impending delays to a project by means of visualization of the movement and color change of the geometric shapes or “blips” on the circular graph.The method comprises extracting information from planning calculations, then translating this information into an animated visual radial graphic display.

A target aggregation method for sea radar detection based on task correlation disclosed in the present invention uses target execution tasks as screening conditions to divide targets into multiple groups; in groups with the same task, set the importance level of each target, and calculate The task correlation between targets, and according to the task correlation, position, speed, heading and other information of the target, calculate the aggregation degree of the target, select the target with the highest aggregation degree as the central target, and transfer other targets within the threshold range of the group to The target aggregates. The method provided by the invention can aggregate a plurality of highly correlated targets into one target, reduce the number of targets displayed on the radar screen, and avoid interference to operators due to dense display of targets.

A normalized radar screen monitoring method includes the steps that S1, the model of a to-be-monitored radar and icon information corresponding to a PPI of the model are determined; S2, according to the determination condition, corresponding radar model information, the icon information and radar image and character data information are extracted from a radar data storage unit; S3, by means of anerected external video data acquisition unit, PPI image videos and PPI display data of the to-be-monitored radar are collected in real time; S4, the collected PPI image videos are subjected to noise removal and de-jittering, image information of a non-PPI part is deleted, target monitoring and target tracking are carried out, and to-be-monitored target data is output; OCR is carried out on the collected PPI display data, and recognition data is output; S5, data fusion is carried out on the target data and the recognition data output in S4 and the information extracted in S2, and a virtual radar image and character report is output and displayed. The technical problem about unified platform display of various kinds of radar system information data is solved, and more visual radar information data is provided for a command and control center.

The invention relates to a life buoy with a reflecting lens structure. The life buoy comprises a life buoy body; a plurality of sections of lenses are arranged in the life buoy body, each section of lens is of a bent cylinder structure, and the lenses are distributed in a circular array by taking the center of the life buoy body as the center, so that the lenses are encircled into a circular ring;the cross section of each section of lens in the radial direction is of a layered structure, and the dielectric constant of the cross section of each section of lens in the radial direction continuously changes from 2 to 1 from the center to the outer layer; a reflector plate is laid on the circumferential surface of each section of the lens, so that a reflector plate covering area and a non-reflector plate covering area are formed on the circumferential surface of the lens, and the surface, attached to the circumferential surface of the lens, of the reflector plate is a reflecting surface. The life buoy has the advantages of being simple in structure, scientific in design, convenient to use, capable of displaying large images on a radar screen and avoiding omission of search and rescue,good in safety, convenient to use and the like.

The invention provides an in-situ outside-casing testing method which overcomes the shortcoming that radar built-in-test (BIT) cannot detect an antenna feed system. By means of a radar power signal-to-noise ratio in-situ testing method, the testing direction is determined through cross scanning, the signal-to-noise ratio is evaluated through a frequency spectrum mode, and outside-casing radiationpower can be accurately measured through a fixed-point high pressure exerting mode. By means of the radar power signal-to-noise ratio in-situ testing method, the shortcomings of the radar BIT are effectively overcome, the antenna feed system of a radar can be checked during maintenance in ordinary time, failure caused by the antenna feed system on the ground is timely removed, and the failure problem that after the radar screened by the method in the sky cannot find the distance descends or cannot find objects is solved. By means of the radar power signal-to-noise ratio in-situ testing method, the antenna feed system failure which cannot be detected by the radar BIT can be removed, and success rate of an airplane executing a task is greatly improved.
