Problems solved by technology

Foreign countries use 8086 microprocessors to process signals. When displaying the same function menu, multiple buttons need to be operated, which makes the operation more complicated; domestic similar products use the same scheme as foreign products, and the interface is English menu, which is more inconvenient to use.

Embodiment Construction

[0012] Such as figure 1 , 2 As shown in , the antenna part includes a C-band planar receiving antenna, a radio frequency cable and a height-adjustable bracket, the host hardware part includes a radio frequency receiving module, a function decoding unit, a computer unit, and a main control self-test unit. The receiving host is connected.

[0013] The radio frequency receiving module includes a radio frequency channel unit, an intermediate frequency unit and a DPSK data demodulation unit. The radio frequency receiving module receives the radio frequency signal of 5031MHz~5090.7MHz, and outputs logarithmic video signal and DPSK demodulation signal after filtering, amplifying, mixing, logarithmic amplification and signal demodulation.

[0014] The functional decoding unit includes functional decoding and envelope information processing functions. After receiving the logarithmic video signal, it measures the signal power, signal angle, basic / auxiliary data words and other paramet...

Abstract

The invention relates to a portable out-field comprehensive test receiver for a microwave landing system. A radio frequency channel is connected with an intermediate frequency unit which is respectively connected with an enveloped information processing unit and a dpsk (Differential Phase Shift Keying) data demodulating and function decoding unit. The enveloped information processing unit is respectively connected with the dpsk data demodulating and function decoding unit as well as a data processing and display unit. The data processing and display unit is connected with an EL (Electroluminescence) display screen and an input interface and control unit. A panel keyboard is connected with the dpsk data demodulating and function decoding unit via the input interface and control unit. The input interface and control unit is respectively connected with the radio frequency channel and a self-detection signal generation unit which is connected with the intermediate frequency unit. The dpskdata demodulating and function decoding unit is connected with a synchronous signal output. The enveloped information processing unit is connected with a log video output. The radio frequency channelis connected with an antenna part. The software process comprises the following steps of: (1) establishing multiple threads and setting initial sending parameters; (2) receiving and judging user input; (3) receiving state information; and (4) receiving measuring data information, and calculating and displaying the received measuring data information. The out-field comprehensive test receiver has the advantages of small size, simple operation and saved flight calibration cost.

Description

technical field [0001] The invention relates to a microwave landing system testing device, in particular to a portable microwave landing system external field comprehensive testing receiver. Background technique [0002] The microwave landing system (MLS) has become the necessary equipment for precision landing guidance of advanced aircraft, and the portable microwave landing system field comprehensive test receiver is one of the necessary equipment for MLS installation and maintenance. Foreign countries use 8086 microprocessors to process signals. When displaying the same function menu, multiple buttons need to be operated, which makes the operation more complicated; domestic similar products use the same scheme as foreign products, and the interface is English menu, which is more inconvenient to use. . Contents of the invention [0003] In view of the above problems, the present invention adopts advanced DSP processing technology to carry out signal processing, and the ...
