Abstract

The present invention relates to an integral and general-purpose radar clutter acquisition simulation emluator and analog simulation process. The present invention includes an industrial control computer, an acquisition card and an analog simulation card, wherein said acquisition card is used f or acquiring clutter signals of radar to the industrial control computer; said industrial control computer is used for executing a clutter simulation according to the clutter signals acquired by the acquire card, executing a clutter emulation according to the input clutter characteristic parameters and outputting the simulation results to an external processing equipment through the analog simulation card. In accordance with the present invention, the unattached clutter collecting device, clutter analogous instrument and clutter emulation mechanism constitute an unified integer, having the advantages such as high speed, large-capacity, universality, flexibility and expandability. The present invention is also characterized in than the acquired true clutter data can be used to execute a analogue simulation.

Description

technical field

[0001] The invention relates to radar clutter signal acquisition, simulation and simulation equipment, in particular to an integrated and general radar clutter acquisition simulation simulator and simulation method. Background technique

[0002] In the existing radar equipment, most of the collection, simulation and simulation of radar clutter adopt separate and dedicated research and development ideas. One is a radar signal acquisition device based on a microcomputer platform and composed of a dedicated acquisition card. This device can collect radar data with 12Bit precision dual channels for specific radar signals. However, the object of its signal acquisition is the zero-IF signal of coherent radar, so its acquisition frequency is only designed to be 5MByte / s, the storage capacity is 1.5Mbyte, and there is no cache device, so its function is single, and it cannot meet the needs of high-speed and large-capacity applications. Radar vi...
