Embodiment Construction

[0019] In order to verify the validity of the non-IID model for the RCS modeling of the cooperative detection network target, the α-μ distribution function, Lognormal distribution function, exponential distribution function, 4°χ 2 The distribution function is used to model the fluctuation characteristics of the target RCS, and the fractional exponential correlation model is used to model the correlation characteristics of the target RCS. The electromagnetic scattering simulation verification experiment for a typical target is as follows:

[0020] When the azimuth observation angle θ∈[0°,30°], such as figure 1 As shown in (a), the fitting parameters of the α-μ distribution are shape parameters α=0.27, μ=5.14, and scale parameters Ω=0.02; the simulation is consistent with each distribution, and it can be seen that the α-μ distribution can be more accurate than other distributions. Good representation of target fluctuation characteristics; when the azimuth observation angle θ∈[4...

Abstract

The invention provides an object modeling method of random configuration of a collaborative detection network. According to random configuration and an object of the collaborative detection network, fluctuating characteristics of different channels of object RCS are modeled into different distribution functions which include different parameters or types of distribution functions, and the problem of modeling random fluctuating characteristic of the object is solved; and correlation of the different channels of object RCS is modeled into fractional-order exponent part correlation, thereby solving the problem in modeling object random correlation, and realizing accurate object modeling of random-configuration collaborative detection network. Further, objects with relatively wide distribution scope and long trailing characteristic suitable for fluctuation of different channels are considered, and a generalized new distribution model provided by the invention can be adapted to more complex objects.

Description

technical field [0001] The invention belongs to radar technology, in particular to target modeling technology in radar cooperative detection network. Background technique [0002] The collaborative detection network is a networked radar detection system that uses multiple radars distributed in different locations in space, multiple frequencies, and multiple polarization modes to implement independent monitoring and collaborative detection of areas of interest. The cooperative detection network has the characteristics of anti-destruction and anti-jamming, detection capability, search speed and enhanced tracking capability. It has broad development space in the joint defense of land, sea, air and space without dead ends. [0003] The cooperative detection network can obtain the multi-dimensional target electromagnetic scattering RCS information of the target in different spatial positions, different frequencies and different polarization modes. [0004] Radar target scatterin...
