Abstract

Problems of creation of models of real time of complex shape targets on the basis of use of their polygonal models are considered. Formulas for radar cross section of multipoint model of target and power of input signal of onboard radar are described. Technique of semi-natural tests of onboard radar detector on the base of multipoint model of target is proposed. Results of digital simulation of input signals of the onboard radar detector of the target from the aerodynamic target on the basis of their multipoint models are given.

Highlights

For simulation and efficiency estimation of onboard proximity radar detectors of targets semi-natural tests are widespread amongst researchers and institutes [1,2]
In case of semi-natural tests for onboard radar detectors imitation of target signal is carried out by calculation of scattering electromagnetic fields from complex shape targets in near zone of radarlocation [3]. Such type of calculation could be developed on the base of exact electrodynamic methods such as method of moments (MoM), Multilevel Fast Multipole Method (MLFMM)
In this paper we have shown that high speed of calculation of input signals of onboard radar detector from complex shape targets could be achieved by use of multipoint model of target

Summary

Introduction

For simulation and efficiency estimation of onboard proximity radar detectors of targets semi-natural tests are widespread amongst researchers and institutes [1,2]. In case of semi-natural tests for onboard radar detectors imitation of target signal is carried out by calculation of scattering electromagnetic fields from complex shape targets in near zone of radarlocation [3]. Such type of calculation could be developed on the base of exact electrodynamic methods such as method of moments (MoM), Multilevel Fast Multipole Method (MLFMM). The polygonal model is practically unsuitable for fast estimation of the operation of onboard radar during its tests at semi-natural stand because of huge computer resources of calculation of targets with large number of polygonal elements even with use of parallel algorithms [5]. Some examples of polygonal models of targets created in Creo Parametric are shown at Figure 1 and Figure 2
