Embodiment Construction

[0047] Since the target radar cross-sectional area RCS is closely related to the target size, structure, and material, the present invention will be further described by taking the three-coordinate radar as an example, based on the target scale information, and using the target RCS characteristic information.

[0048] (1) Generalized dot trace generation

[0049] Suppose there are M targets in the monitoring space, and the radar trace in the narrow sense is:

[0050] Yi (k)=(R i , α i , β i ) i=1, 2, . . . , M (11)

[0051] where R i 、α i , β i are the distance, azimuth, and elevation values ​​of the i-th generalized trace at time k, respectively. Its data format is shown in Table 1:

[0052] Table 1 Narrow sense dot plot data format

[0053]

[0054] Let any target RCS characteristic value be A gi (k), keep the narrow dot plot format and the number of columns unchanged, increase the number of rows by one dimension, and add the RCS characteristic information A gi...

Abstract

The invention discloses a generalized grouping detection method which includes the following steps: S1. generalized point trace generation; S2. generalized grouping detection criteria; and S3. generalized grouping detection algorithm. The generalized point trace enables grouping detection to have selectivity, which increases anti-interference capability. The generalized grouping detection criteria enable the grouping detection to be flexible, which increases object identification capability. The generalized grouping detection algorithm enables the grouping detection to have generability, which increases situation cognition capability. The generalized grouping detection algorithm is not only applicable to narrow band radar object tracking and broadband radar object tracking, and is also applicable to object tracking of visible light sensors, infrared sensors and multispectral sensors, etc. The generalized grouping detection algorithm is applicable to single object tracking, and is also applicable to multi-object tracking. The generalized grouping detection algorithm is applicable to dense multi-object tracking and is also applicable to sparse multi-object tracking. The generalized grouping detection algorithm is applicable to group object tracking of physical domain and is also applicable to group object tracking of functional domain. The generalized grouping detection method can increase capabilities of exploration systems for objects on land, on air, at sea, near space and outer space, etc, and can simplify commanding and controlling systems.

Description

technical field [0001] The invention relates to the field of information processing, in particular to the field of situation awareness of radar and optical system target tracking and command and control systems. Background technique [0002] Group targets, also known as group targets and target groups, refer to a collection of multi-targets that satisfy a given target distance criterion and maintain a relatively stable spatial position for a long enough time. Among them, single targets and formation targets are special cases of group targets. . The process of group target tracking can be summarized as follows: ① Divide dense multi-targets into indistinguishable dense multi-target clusters and distinguishable single targets, that is, cluster detection; ② use indistinguishable dense multi-target clusters as group targets according to certain rules Processing; ③Track group targets and distinguishable single targets as sparse multi-targets. Therefore, group detection has becom...
