Antennal control system software in telemetry ground station adopts C# language to realize switching of various tracking modes and monitoring of working state. The software running on the controller and jade on the data of multiple interfaces on the base of the original data storage, analysis, real-time calculating target azimuth and pitch information output to the servo control system, puts forward all kinds of control functions and strategies of telemetry antenna, complete antenna precision of target tracking, real-time display the running state of the system software at the same time, and timely response to abnormal situation. The practical application results show that the software has high reliability and expansibility, and can fully meet the needs of real-time control system, and has good practicability and development prospects.
The implementation of digital fraction delay has found diverse applications in signal processing, leading to extensive research in this area. To improve the accuracy of channel estimation in practice, Fractional Delay Finite Impulse Response (FD FIR) filters have been proposed. This paper presents the implement principle of fractional delay FIR filters. Building upon existing solutions, it makes improvements to the methods of windowed sinc function, smooth transition function, complex general LS design, and maximally flat design: Lagrange interpolation from simplicity, efficiency, and filter performance, particularly in the reduction of Gibbs phenomenon caused by truncation in time domain. The effectiveness of the proposed method is validated through MATLAB simulation and comprehensive magnitude response analysis, which demonstrates that the complex LS design exhibits the best response with a wider passband and almost no ripple or Gibbs phenomenon.
