Problems solved by technology

[0005] The purpose of the present invention is to propose a false target elimination method under radar networking to solve the problem of target position data collected by multiple radars due to the different accuracy of the radars when observing the same area for multiple radars in the existing network. False targets are generated due to differences, which in turn affects the correct judgment of the current battlefield situation

specific Embodiment approach 1

[0034] Specific implementation mode one: the following combination figure 1 , figure 2 , image 3 , Figure 5 Describe this implementation mode, a method for eliminating false targets under a radar network described in this implementation mode, comprising the following steps:

[0035] Step 1, constructing a general radar communication protocol template, utilizing the communication protocol template to obtain radar target data;

[0036] In order to realize the acquisition of radar data of various communication protocol types, a general radar communication protocol template is constructed, and a three-level hierarchy of data frame, data element, and data element bit is used to describe various radar communication protocols uniformly. In the general radar communication protocol In the template, the data frame is the complete target data protocol output by the radar, including the warning radar new 97, the original 97, the target track report, the measurement radar intelligenc...

specific Embodiment approach 2

[0060] Specific implementation mode two: the following combination Figure 4 Describe this embodiment, the difference between this embodiment and the specific embodiment one is: the specific method of adding the corresponding data frame according to the radar communication protocol type described in step one is as follows:

[0061] Fill in the source device according to the source in the communication agreement;

[0062] Fill in the target device according to the destination in the communication agreement;

[0063] Fill in the dynamic frame identifier according to whether the length of the communication protocol is fixed. For a communication protocol with an unfixed length, fill in the position of the number of dynamic frames according to the number in the communication protocol, and fill in the dynamic frame upper limit according to the maximum value in the communication protocol. For communication with a fixed length Agreement, do not fill in the location of the number of d...

[0067] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: according to the attribute information unit in the radar communication protocol described in step one or two, the specific method of adding data elements under the data frame is as follows:

[0068] Fill in the ID according to the attribute number;

[0069] Fill in the name according to the attribute name;

[0070] Fill in the type according to the data type of the attribute;

[0071] Fill in the length according to the data type length of the attribute;

[0072] Fill in the optional identifier according to whether the attribute must appear. For the attribute that does not have to appear, fill in the leading character type according to the data type of the symbol before the attribute, fill in the leading character length according to the data type length of the symbol before the attribute, and fill in according to the value of the symbol before the attribute Preamb...

Abstract

The invention discloses a method for eliminating a false target under radar networking, and belongs to the technical field of radar target information processing, which is used for solving the problems that when existing multiple networking radars are used for observing the same region, a false target is generated because the precisions of the radars are different and the target position data acquired by the multiple radars are different, and further the correct judgment of the current battlefield situation is affected. According to the key point of the technical scheme, the method comprises the following steps: constructing a universal radar communication protocol mold plate, and acquiring the radar target data by utilizing the communication protocol mold plate; associating target data information; measuring the target data similarity; and integrating the target data after the target data similarity is measured. According to the invention, the false target generation probability is reduced by around 50%, and the false target generation probability under the radar networking condition is reduced. The method is mainly applied to the military radar target information processing process, and also can be extensively applied to the multi-sensor information integration process in the measurement process.

Description

technical field [0001] The invention relates to a method for eliminating false targets under radar networking, and belongs to the technical field of radar target information processing. Background technique [0002] Radar is the "clairvoyance" of modern weapon systems, and its main functions are to search, discover, capture, track, and measure targets. In modern warfare, radar can provide all kinds of information required by the battlefield with high precision, over-the-horizon, all-weather, and is the core of the informationized combat system. Since the birth of the first radar during World War II, the increasingly detailed and comprehensive air situation requirements have continuously promoted the development of radar technology. Today, the battlefield of modern warfare has expanded to land, sea, air, sky, and electromagnetic five-dimensional space. The birth of high-tech weapons, especially precision-guided weapons and long-range strike weapons, has made radar a target f...
