Detailed Description
In order to facilitate clear description of technical solutions of the embodiments of the present invention, in the embodiments of the present invention, terms such as "first" and "second" are used to distinguish the same items or similar items having substantially the same functions and actions. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and the order of the thresholds is not limited. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.
It is to be understood that the terms "exemplary" or "such as" are used herein to indicate examples, illustrations, or illustrations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the present invention, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of single item(s) or multiple items(s). For example, at least one (one) of a, b, or c, may represent: a, b, c, a and b combination, a and c combination, b and c combination, or a, b and c combination, wherein a, b and c can be single or multiple.
The current common target threat assessment method mainly comprises fuzzy logic, a neural network, a multi-attribute decision method, evidence, a Bayesian network theory and the like. Most of the methods need to introduce expert knowledge to construct rules or reasoning networks, and from the cognitive perspective, the methods form thinking of a target threat degree evaluation process according to the fusion processing of known information and data. The Bayesian network is similar to a neuron network, can describe the human reasoning process, and is suitable for threat degree evaluation of targets in complex environment; compared with fuzzy logic, the Bayesian theory has strict mathematical and statistical bases, and the inference model has universality and can effectively unify the prior information and the posterior information, so that the evaluation result has time continuity and accumulative property and is convenient for dynamic extension. The method is mainly embodied in a target classification identification technology, a target multi-feature parameter extraction technology and a target data fusion technology.
The target evaluation method is mainly applied to the air target, the ground radar and the air radar have different application scenes, and the motion characteristics of the ground target and the air target are greatly different. Because the ground radar has a complex working environment, various types of targets and variable motion characteristics, the evaluation of the threat degree of the ground radar target is difficult to use by the method for evaluating the threat degree of the air radar target. Therefore, the ground radar evaluates the threat degree of the target, and early warning is performed through the evaluated threat degree, so that the early warning is one of the key problems which are urgently needed to be solved.
In view of the above problem, fig. 1 illustrates a flowchart of a threat disposal starting method for a ground target according to an embodiment of the present invention. The threat disposal starting method of the ground target provided by the embodiment of the invention is applied to ground radars. As shown in fig. 1, the threat disposal initiating method of the ground target includes the steps of:
step 11: the radar device receives radar signals of a radar ground target. The radar signal is substantially a radar echo signal.
In practical applications, the basic task of radar is to detect suspicious targets and determine the state parameters of the targets, such as distance, speed, etc. The radar mainly comprises an antenna, a transmitter, a receiver, a signal processor, a display and the like. The radar transmitter generates enough electromagnetic energy to be transmitted to the antenna through the transceiving switch. The antenna radiates the electromagnetic energy into the atmosphere, concentrates the electromagnetic energy in a certain narrow direction to form a wave beam, and forwards propagates the wave beam. After the electromagnetic waves encounter a target in a wave beam, reflection is generated along all directions, and a part of electromagnetic energy is reflected back to the direction of the radar and is acquired by the radar antenna. The energy obtained by the antenna is transmitted to the receiver through the transmitting-receiving conversion switch to form an echo signal of the radar.
Step 12: the radar equipment determines attribute parameters, state parameters and motion parameters of a radar ground target relative to a guard ring area according to a radar signal of the radar ground target, and determines a plurality of dimensionality reference values of the radar ground target according to the attribute parameters, the state parameters and the motion parameters of the radar ground target;
in practical application, as the main task of the ground radar is to monitor the ground target dynamic state, the threat is found and early warning is carried out, and a corresponding warning area is set according to the actual condition. For example: plant areas, warehouse areas, office areas and other important places. The signal processing in the ground radar extracts the information contained in the echo, which is also the attribute parameter, the state parameter and the motion parameter of the ground target relative to the warning area.
The parameters of the radar target are many and are related to the system of the radar, and since the application scene is the radar ground target, only the ground radar is discussed to obtain the parameters of the ground target. These parameters are selected and designed based on the tactical performance of the ground radar and the ground targets, and thus, each parameter of the selected ground target has a particular context.
Illustratively, the state parameters include: the radar ground target position information, the azimuth information and the distance information, and the motion parameters comprise the motion direction information and the motion speed information of the radar ground target; the attribute parameters include: type information of radar ground target.
In practical applications, the position information of the radar ground target may be coordinates of the radar ground target, the distance information may be a distance of the radar ground target from a specific position in the warning area, and the movement direction information of the radar ground target may be a movement direction of the radar ground target relative to the warning area, for example, toward the right side of the warning area. The parameters of the radar ground target are not limited to the above-mentioned parameter information, and may be specifically set according to the actual motion condition of the radar ground target and the types of parameters that can be monitored by the radar.
In an alternative form, the alert zone includes at least one primary feature. The multiple dimensional reference values of the radar ground target comprise: the method comprises the steps of obtaining a radar ground target safety level reference value, a time reference value of the radar ground target reaching at least one destination, a meeting probability reference value of the radar ground target and at least one destination, a radar ground target type reference value and a safety level reference value of a region where the radar ground target is located.
In practical applications, fig. 2 illustrates a schematic diagram of a target situation artifact provided by an embodiment of the present invention, as shown in fig. 2, the warning area may include an entire large area such as the factory floor, the warehouse floor, and the office floor, but a specific location of the factory floor, the warehouse floor, and the office floor may be a key location of the warning area, or may be a key location of one of a plurality of buildings in the factory floor, and the present invention is not limited thereto.
Step 13: the radar equipment determines a threat degree value of the radar ground target according to the multiple dimension reference values of the radar ground target. The threat level values of the radar ground targets can be expressed by various parameters as long as the threat level values of the radar ground targets can be represented.
Step 14: and the radar equipment starts the threat disposal plan under the condition that the threat degree value of the radar ground target is matched with the plan starting condition.
The predetermined starting condition may be greater than or equal to a predetermined threat level value, or greater than or equal to a predetermined threat level.
When the starting condition of the plan is greater than or equal to the preset threat degree value, the matching of the threat degree value of the radar ground target and the starting condition of the plan refers to:
and the threat degree value of the radar ground target is greater than or equal to the preset threat degree value.
When the predetermined starting condition is greater than or equal to the predetermined threat level. Matching the threat degree value of the radar ground target with the starting condition of the plan refers to:
the threat level of the radar ground target is greater than or equal to a preset threat level. At this time, the threat level value of the radar ground target needs to be converted into the threat level of the radar ground target. Specifically, the radar apparatus, in a case where the threat degree value of the radar ground target matches the plan start condition, starting the threat disposal plan includes:
the radar equipment determines the threat level of the ground target from the first preset corresponding relation according to the threat degree value of the radar ground target; the first preset corresponding relation comprises a corresponding relation between a threat degree value range and each level of threat level;
in practical application, for example, the target threat level is defined to be divided into 5 levels, the 5 th level is the highest level, the color is marked as red, the threat level is 'critical', and the rest levels are sequentially the 4 th level orange and serious; grade 3 yellow, dangerous; level 2 blue, normal; level 1 green, no threat. Table 1 illustrates a comparison table of threat level of each level and a target threat degree value range.
TABLE 1 comparison relationship table between threat levels and target threat degree value range
| Threat level | Stage 5 | Stage 4 | Stage 3 | |
Stage 1 |
| Target threat level value range | >70 | 50-70 | 30-50 | 10-30 | <＝10 |
As shown in table 1, when the target threat level value range is greater than 70, the threat level is level 5, which is critical; when the value range of the target threat degree value is between 50 and 70, the threat level is level 4 and is serious; and so on. The specific numerical values in table 1 are not limited thereto.
Step 142: and starting a threat disposal plan under the condition that the radar equipment determines that the threat level of the ground target is greater than or equal to the preset threat level.
In practical application, if the preset threat level is level 3, when the threat level of the ground target is level 3, starting a threat disposal plan; a threat handling protocol may also be initiated when the ground target has a threat level of 4, but may not be initiated when the ground target has a threat level of 1.
The threat disposal plan can be an emergency alarm bell alarm, report to a command center and the like.
For example: the method comprises the following steps that a vehicle runs around a border, a ground radar finds the vehicle through radar signals and tracks the vehicle, the vehicle is outside a warning area at first, the running speed is low, the radar evaluates all parameters of the vehicle, and the threat level of the vehicle is defined as level 1 without threat; after a period of time tracking, the vehicle enters a warning area and directly drives to a command center, the threat level is rapidly improved to 3, if the preset threat level is 3, a threat plan is immediately started, and a guard notifies each barrier to carry out manual interception and prepares to take emergency measures at any time.
As shown in FIG. 2, a ground radar is installed at the origin of coordinates (0, 0), and the coordinates of important places such as a warning area, a warehouse area, an office area, and a factory area are (x)0，y0)、(x1，y1)、 (x2，y2) The surrounding situation, radar ground target has target 1, target 2, target 3 and target 4, neither target 1 nor target 2 is in the alert zone, target 3 is around the reservoir zone of the alert zone, and target 4 is around the office zone.
Illustratively, the method of determining the time reference value comprises:
determining the time length of the radar ground target reaching at least one destination according to the distance information of the radar ground target and the movement speed information of the radar ground target;
determining a time reference value of the radar ground target reaching at least one destination from a second preset corresponding relation according to the time length of the radar ground target reaching the at least one destination; the second preset corresponding relation comprises a corresponding relation between the arrival duration and the time reference value.
In practical application, as shown in fig. 2, each radar ground target has a corresponding distance to each of the warning areas, and the arrival time from the target to the destination can be obtained according to the distance from the target to the destination and the movement speed of the target, wherein different arrival times correspond to different time reference values. Table 2 illustrates a correspondence table of the arrival time length and the time reference value.
TABLE 2 table of correspondence between arrival time and time reference value
As shown in table 2, the arrival time was less than 3 minutes, and the time reference value was 5; it can be seen in turn that the shorter the arrival time duration, the larger the time reference value, and the longer the arrival time duration, the smaller the time reference value. The specific numerical values in table 2 are not limited thereto.
Illustratively, the method for determining the encounter probability reference value includes:
according to the azimuth information of the radar ground target and the movement direction information of the radar ground target, obtaining an included angle between the movement direction of the radar ground target and the direction of the radar ground target and at least one place;
determining an encounter probability reference value of the radar ground target and at least one wanted ground from a third preset corresponding relation according to the included angle; the third predetermined correspondence includes a correspondence of the included angle to at least one reference value of the probability of meeting.
In practical application, as shown in fig. 2, the moving direction of the object 1 is consistent with the direction from the object 1 to the destination of the warehouse, and it can be considered that the included angle from the moving direction of the object 1 to the destination of the warehouse is 0 degrees, the moving direction of the object 1 is not consistent with the direction from the object 1 to the destination of the factory, the included angle is a1, the moving direction of the object 1 is not consistent with the direction from the object 1 to the destination of the office, and the included angle is a 2; the moving direction of the target 2 is inconsistent with the direction from the target 2 to the destination of the warehouse area, the included angle from the moving direction of the target 2 to the destination of the warehouse area is b1, the moving direction of the target 2 is inconsistent with the direction from the target 2 to the destination of the factory area, the included angle is b2, the moving direction of the target 2 is inconsistent with the direction from the target 2 to the destination of the office area, and the included angle is b 3; similarly, the included angles between the moving directions of the objects 3 and 4 and the directions from the objects to the primary site of the warehouse area, the primary site of the factory area and the primary site of the office area can be obtained. The closer the included angle is to 0 degree, the greater the possibility that the target is rushing to the ground is, so as to calculate the reference value of the meeting possibility of the target and the ground, and table 3 illustrates the correspondence table between the included angle and the reference value of the meeting probability provided by the embodiment of the present invention.

In practical applications, table 4 exemplifies a correspondence table between radar ground target type information and radar ground target type reference values, and as shown in table 4, the reference value of the vehicle is the largest, the reference value of the person is centered, the other types are the smallest, and the specific target type information and target type reference values in the table are not limited thereto.

| Radar ground target type information | Radar ground target type reference value |
| Vehicle with wheels | 0.9 |
| Human being | 0.6 |
| Others | 0.1 |
The method for determining the safety level reference value of the area where the radar ground target is located comprises the following steps:
determining a corresponding regional safety level according to the position information of the radar ground target, and determining a regional safety level reference value of the radar ground target from a fifth preset corresponding relation according to the regional safety level; the fifth preset corresponding relation comprises a corresponding relation between the regional security level and the regional security level reference value.
In practical applications, according to experience, regional security levels are set for different regions, as shown in fig. 2, the library area, the factory area and the office area have different importance levels, and the library area, the factory area and the office area are centered on the respective places, and the inside and the outside of the library area, the factory area and the office area can be divided into three layers, wherein the closer to the place, the higher the regional security level is, the farther from the place, the lower the regional security level is. Therefore, the position information of the ground target can be longitude and latitude, the specific position of the ground target in the warning area or around the warning area can be known according to the longitude and latitude, and the regional safety level of the ground target is determined according to the comprehensive factors. Table 5 illustrates a correspondence table between the regional security level and the regional security level reference value, and as shown in table 5, the regional security level is obtained by integrating the specific regional position and the circle layer located in the region, and the higher the regional security level is, the higher the corresponding regional security level reference value is.

The specific values and the preset systems in the comparison tables in the invention can be adjusted according to actual conditions or experience, and are not limited to the numerical values in the embodiments.
