Simulation method for high dynamic target characteristics of onboard responder

Abstract

The invention discloses a simulation method for high dynamic target characteristics of an onboard responder. An unmanned aerial vehicle and an airborne responder are used for simulating a high dynamictarget, and a measurement and control experimental verification and training test is completed by combining a ground measurement and control station: the unmanned aerial vehicle is controlled to enable the unmanned aerial vehicle to be in a straight line where the position of the simulated high dynamic target flight path at the moment is connected with the ground measurement and control station;when the flight path of the unmanned aerial vehicle is limited by limit parameters and continuous simulation cannot be completed, a flight path segmentation simulation and splicing processing mode canbe adopted; the transmitting and receiving frequency forwarding ratio of the onboard responder is adjusted in real time and round-trip doppler frequency introduced by the high dynamic target in a continuous wave measuring system is restored, so as to complete the simulation of a high dynamic target speed measuring element; and the transmitting and receiving signal delay time of the onboard responder is adjusted in real time, and signal round-trip propagation and forwarding delay introduced by the high dynamic target in a pulse measuring system is reduced, so as to complete the simulation of ahigh dynamic target distance measuring element.

Description

Technical field [0001] The invention relates to the field of aerospace simulation technology, and in particular to a method for simulating the characteristics of an airborne transponder to a high dynamic target. Background technique [0002] In the process of development and use of high dynamic target measurement and control system, the development and use of high dynamic target has problems such as high cost, difficulty, and low fault tolerance. Before the actual measurement and control task of high dynamic target, it needs to be completed in some way. The joint debugging of the dynamic target and the ground measurement and control system and the inspection of the working status of the equipment; the existing conventional method is to provide the measurement and control system with a signal that simulates the high dynamic target through a direct computer connection to verify whether the system is working properly.

Problems solved by technology

[0004] This method can verify the basic functions of the measurement and control system, but it cannot completely simulate the working state of the measurement and control system in actual work; therefore, it is necessary to design a new method that can replace the joint test of the high dynamic target and the measurement and control system at a relatively low cost , simulate the working state of the measurement and control system, and realize the overall function verification of the measurement and control system
