Satellite-borne measurement and control receiver

Abstract

The invention relates to a satellite-borne measurement and control receiver and belongs to the technical field of remote measurement and remote control. The satellite-borne measurement and control receiver comprises a receiving channel part and a digital processing part; the receiving channel part comprises a frequency mixer, a filter, a power divider, a narrow-band band-pass filter, an automatic gain control amplifier and a wide-band band-pass filter; and the digital processing part comprises an analog digital converter and an FPGA (Field Programmable Gate Array). The satellite-borne measurement and control receiver disclosed by the invention adopts two filtering amplification branches; in a digital processing method, double A/D (Analogue/Digital) are used for sampling; a narrow branch assists a carrier synchronization method of a wide branch to obtain the high sensitivity and consider the requirements of broadband distance measurement; after a frequency Doppler and a phase of a main carrier are eliminated, and remote control demodulation and distance measurement demodulation adopt a full-digital structure to realize digital realization of a plurality of demodulation systems and distance measurement signal formats; and the whole performance and the expandability of a responder are improved.

AI Technical Summary

Benefits of technology

This technology uses both different types of filters for data transmission: one type called filter B (Branch) helps with wider range signals without affecting their quality or resolution. Another type called Filter C (Cube), also known as Carryer Synchronized Sampling Amplifier (CSMA). It achieves this by combining dual analogue samples from each channel together through a special circuit that improves its response time when transmitting over long distances. Remote detection involves converting received radio waves back onto electrical fields before being detected on receivers' antennas. Overall, these technical improvements help make communication devices more sensitive at longer ranges than traditional methods like AMR and LORA.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving upon existing receivers for measuring astronomy targets such as those at depths greater than 10 meters or beyond that can cause interference between signals transmitted through different paths due to factors like atmospheric turbulence (AT), ground penetration radars (GPRS). Current solutions are limited because they cannot achieve both high sensing performance and wide range coverage simultaneover without increasing their size.
