Description

This utility model relates to radio engineering, in particular to radar, and can be used in aerological radiosondes (ARZ) of atmospheric radiosonde for measuring ranges to ARZ, and can also be used to build highly stable and economical transceivers of communication systems.

Radiosonde transceivers are known whose microwave modules are built on self-oscillators operating in a super-regenerative mode [1] - [7].

A disadvantage of the aforementioned super-regenerative transceivers for a radio probe is the use of a super-regeneration mode, which is implemented on a functionally complete transmit-receive module with the impossibility of separately configuring the receiving and transmitting path, which makes tuning the radio probe a complex technological procedure performed by highly qualified personnel.

The problem to which the claimed utility model is directed is to reduce the complexity of adjusting the radiosonde.

This problem is solved due to the fact that the claimed microwave module of the radiosonde contains an antenna, a low-noise amplifier, a detector, a threshold device, a microprocessor, a modulator and a transmitter, the antenna being configured to transmit a signal to a low-noise amplifier that transmits this signal to a detector with a logarithmic gain dependence and then to the input of a threshold device that controls the operation of a microprocessor that generates signals for a modulator that modulates the transmitter, the output of which is connected to the ant no. Thus, the receiver and transmitter in the inventive microwave module of the radiosonde are separate functionally complete nodes, which allows them to be separately configured and reduce the complexity of adjusting the radiosonde. In order to reduce the mutual influence of the receiving and transmitting parts of the microwave module, the antenna can be made in the form of two emitters spaced in space.

The essence of the utility model is illustrated in figure 1.

The device operates as follows:

The signal from the antenna (A) is fed to a low-noise amplifier (LNA), which serves to increase the sensitivity of the receiver. Then the signal goes to the detector (D) with a logarithmic dependence of the gain, after which the signal goes to the threshold device (PU) with an adjustable threshold. The threshold device generates an impulse to turn on the transmitter (PER). The transmission is carried out when a signal arrives at the receiving part of the module and the threshold device is triggered. Information from sensors connected by their output to the microprocessor (MP) input is converted by the MP into digital form, and, through a modulator (MOD), is transmitted to the microwave module and performs amplitude modulation of the transmitter carrier frequency. The transmitting part is based on a feedback generator with the possibility of modulation by direct current. The carrier frequency of the response pulse must correspond to the frequency of the probing signal.

The technical result provided by the microwave module design is:

- the ability to separately configure the receiving and transmitting parts of the microwave module, which significantly reduces the complexity of the ARZ adjustment, and, therefore, reduces the requirements for the qualification of staff;

An example of a specific embodiment of a utility model is the manufacture of an ARZ microwave module without using a super-regeneration mode with a sensitivity of up to - 90-100 dB / W with an average radiation power of 180-250 mW and an efficiency of at least 25%. This ARZ transceiver provides accurate measurement of the slant range from the ground radar to 200-300 km with an accuracy of no worse than ± 15 m, with a low level of request power, which corresponds to the technical requirements of Roshydromet for ARZ [8]. So the pulse power of the radar transmitter is 200 watts, the average is 0.2 watts. ARZ telemetry signals are transmitted at the same frequency by frequency modulation of superimposing pulses, that is, all ARZ coordinates are measured at one carrier frequency: elevation angle, azimuth, range, and meteorological value telemetry signals are transmitted [9].

It is supposed to introduce a utility model on the aerological network of the Russian Federation.
