Antenna identification method applicable to portable radio monitoring one-body machine

Abstract

The invention discloses an antenna identification method applicable to a portable radio monitoring one-body machine. The method comprises directional antenna identification steps that: A, a scanning casing connector determines whether connection of a directional antenna and the casing connector through an antenna connector occurs, if access of the directional antenna does not occur, scanning continues; B, if access of the directional antenna occurs, when a signal processing unit contacts with one of two contacts on the casing connector through a coding board in an antenna connector connection chamber, an antenna mounting direction value of a horizontally-mounted antenna is read; when the other coding board contacts with the other contact of the two contacts, an antenna mounting direction value of a vertically-mounted antenna is read; the signal processing unit reads a polarized direction of the directional antenna utilized by a present system through reading the antenna mounting direction values; and C, the signal processing unit further reads an antenna coding value through the contacts and the coding board; the signal processing unit reads a type of the directional antenna utilized by the present system through the antenna coding value.

Description

technical field [0001] The invention relates to a radio monitoring method, in particular to a method suitable for a portable radio monitoring all-in-one machine to identify antenna types. Background technique [0002] At present, the vast majority of portable receiving antennas do not have the antenna type identification function, such as the HE200, HE300 and other handheld antenna series produced by the German R&S company; and the IDA-3106 interference directional analyzer produced by the German NARDA company is equipped with a handheld antenna , began to have a simple antenna type identification function, through the protruding part on the antenna plug, contact the corresponding coding switch in the antenna socket on the casing, to identify the installation position of the antenna and the type of antenna; it is also currently only available Hand-held antenna with antenna polarization identification function; however, due to the narrow space in the antenna socket, the conta...

AI Technical Summary

Problems solved by technology

[0004] Before the appearance of the portable radio monitoring all-in-one machine that the applicant applied for at the same time, the existing portable radio monitoring system was mainly composed of several major components such as a signal processing unit, a receiver, an electronic compass and an antenna; the radio signal induced by the antenna was connected to the receiver, The intermediate frequency signal of the receiver is processed by FFT and then output to the signal processing unit. The signal processing unit outputs the parameters of the signal to the display for display after data calculation according to the direction indication of the electronic compass; The problems of split-type radio monitoring equipment composed of several major components such as compass and antenna include: 1. The radio monitoring equipment is formed by split-type combination, which is particularly inconvenient to carry and use; 2. A large number of connectors are required between multiple components, resulting in The concealment of radio monitoring equipment is poor, and the failure rate of each component is high; 3. The lack of antenna monitoring function module makes it impossible to detect and analyze the antenna for immediate use; Receiving terminal for information transmission

The disadvantage of the product of this patent is that the user also needs to wear information processing devices, antennas, electronic compass and other equipment to form a radio monitoring system that can monitor radio signals; however, since the direction finding host and information processing devices are separate When performing radio monitoring, the user needs to hang or carry it on the body respectively, and then carry out radio monitoring through the hand-held antenna. Such a structure is not only complicated, but also has a single function, poor operation concealment, and portability. Poor; and does not have the identification function of directional antenna
