IFF responder boundary test method

Abstract

The invention discloses an IFF responder boundary test method, and aims to provide a boundary test method which is high in test efficiency and has accuracy. The method comprises the following steps that: firstly, an industrial personal computer with built-in automatic test software, a signal source connected with a switch matrix in series and a signal analyzer are connected to form an identification friend or foe (IFF) responder boundary test system which performs bidirectional communication with a responder through the switch matrix; and automatic test software controls a signal source to automatically and continuously generate various excitation signals of various widths and amplitudes through an internet access of an industrial personal computer and the switch matrix to automatically generates pulse inquiry signals of various modes, an upper antenna and a lower antenna which are connected with a responder through the switch matrix are used for carrying out boundary test on an inquiry signal pulse signal and a sidelobe suppression signal under various pulse characteristic conditions on the responder, the boundary value of the responder for receiving and processing the inquiry pulse signal is determined based on the inquiry signal pulse characteristic, and whether the response function and the sidelobe suppression function of the responder can work normally or not is judged.

Description

technical field [0001] The invention relates to a boundary test method for the receiving capability of an IFF (IFF) transponder of Mark series IFF systems of the western system. Background technique [0002] In order to meet the needs of future digitalization, the system with identification friend or foe (IFF) capability has become one of the basic functional units of the digital system in the 21st century. At present, the identification friend or foe system is composed of two parts: one is directly used by the user to identify unknown targets, which is called the direct sub-system; the other provides potential information about the target to the user, and the computer can identify it by analyzing and judging the information. This part is called indirect subsystem. The direct sub-system is further divided into two types, one requires the cooperation of the target and the other does not require the cooperation of the target, such as primary radar, this technology does not re...
