摘要
Abstract
The paper researches abnormal telemetry signals recognition method to check the possible random failure which could result in telemetry signals abnormity during ground testing and inorbit operation of satellite and to find out the problems quickly and accurately.The paper summarizes three abnormal situations in telemetry receiving process by analyzing the characters of BPSK/PM signals,puts forward a recognition method based on parameter estimation and finishes emulation proof.The application of the method establishes foundation for storage and disposal of abnormal signals afterward and provides data support for trouble determinant.关键词
