Starting relations are obtained for the coupling influence analysis between an oscillator and an antenna for autodyne transponder features in the mode of frequency locking by the request radar signal. The operation speed investigation results show the dependence upon a coupling degree and the oscillator operation mode as well as on the value of the “softness” index of the impedance characteristic...
The paper presents the results of development of the coherently-pulse transmitter of aerological radar of system of radio sounding of the atmosphere with phase modulation of sequence of the request radio impulses, providing measurement of instantaneous velocity and inclined range to an aerological radiosonde (ARZ) supplied with the super-regenerative transceiver (SPP).
Information concerning the development of the upper-air sounding system for meteorological provision of the ??Vostochny?? cosmodrome, integrating the most advanced atmosphere parameter instrumentation is provided in the present paper. Complex use of sounding means allows moving to a qualitatively new level in operational data acquisition about an atmosphere state.
Research problems of atmosphere parameter measurement accuracy of the radar and radio navigational upper-air sounding system (UASS) are discussed in the report. Procedures of laboratory tests and comparative launch execution are developed to carry out research. Laboratory and comparative testing of the navigational UASS with AVK, MARL-A and Vector-M radar-tracking systems are carried out. It is shown...
The methods of decreasing of shock oscillations of starting current in the receiving mode of the superregenerative transceiver of a radiosonde are considered.
Historical background is given, the analysis of current state is performed and the ways of further development of atmosphere radiosounding systems are presented. Alongside with the prospects, the advisability of developing and implementing the digital mobile system using the signals of satellite navigation GLONASS/GPS platform for tracking radiosounding and determining its location, as well as direction...
The description of the functional block diagram and the operating principle of the transceiver of radiosonde MRZ-3MK operating in the autodyne mode is introduced. The results of experimental research of the autodyne oscillator operation of this radiosonde in the mode of receiving uplink radar request signal.
This report describes the operation principle and block diagram of the autodyne transceiver proposed for the atmosphere radio probing system. The transceiver has better electromagnetic compatibility as compared with currently used superregenerative devices. There are theoretical investigation results of the autodyne operating mode as a receiver of signals from a requesting radar.
The results of researches of an error of measurement by means of the pulse method of an inclined range to the aerological radar radiosonde are considered.
The problems of formation and reception of a reciprocal signal of the superregenerative transceiver of an aerological radiosonde in the channel of measurement of the inclined range of the aerological coherent radar are discussed.
The problems of computer modeling concerning the influence of shock fluctuations of starting current in the oscillatory contour upon auto-oscillatory process development in pulse generators and super-regenerative transceivers are considered.
The influence of starting current fluctuations of the super-regenerative transceiver on the pass-band and sensitivity in a reception mode is observed. 1. The parameters of a reception mode — sensitivity and pass-band are defined by the law of change of attenuation of a contour, near a boundary value. 2. The influence of starting current fluctuations on statistical characteristics of attenuation of...
