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...

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...
