A ku-ka band frequency conversion device for hardware-in-the-loop simulation of missile guidance system

Abstract

The invention belongs to missile simulation technology, and relates to a Ku-Ka band frequency conversion device for semi-physical simulation of a missile guidance system, including: a public reference source [1]: providing a frequency reference for the entire frequency conversion device; a down-conversion component [2]: used for The Ka-band reference signal from the radar seeker is down-converted to the Ku-band; the up-conversion component [3]: is used to up-convert the Ku-band signal processed by the target echo simulator to the Ka-band; a missile guidance of the present invention The special Ku-Ka band frequency conversion device for system hardware-in-the-loop simulation is attached to the target echo signal simulator, and the target echo signal simulator can be changed without affecting the function and performance of the Ku-band target echo signal simulator. The operating frequency enables it to work in the Ka band. The operation method of the invention is simple, has high reliability, and can make full use of equipment resources.

Description

A Ku-Ka band frequency conversion device for hardware-in-the-loop simulation of missile guidance system technical field The invention belongs to missile emulation technology, relate to a kind of missile guidance system semi-physical emulation with Ku-Ka band frequency conversion device. Background technique Radar type air-to-air missile guidance system semi-physical simulation is used for simulating missile flight and attack target process, detects mine The performance of the Da-type air-to-air missile guidance system provides a basis for the design and index optimization of the missile guidance system. Department of hardware-in-the-loop simulation The target echo signal simulator in the system is used to simulate the target echo signal and reproduce the echo's amplitude, frequency, time domain delay and other characteristics. sex. For the target echo simulator working in the Ku-band, it can only meet the test and Simulation needs. Once the working frequency ban...
