The Calculation Of The UAV Remote Control And Telemetry Detection Distance

The UAV detection distance of remote control and telemetry is an important character of the remote control and telemetry system。Calculating the detection distance by the actual circumstance is of great significance for UAV flight safety and system reliability。This paper is mainly deals with the parameter L∑of the detection distance equation,using mathematic modeling that can improve the precision of computing。With the detailed analysis of the remote control and telemetry equation,we can find that the electric wave interference and medium absorb are the important aspects that influence the detection distance of the UAV。With the calculation of electric wave interference,we mainly consider the multipath effect and choose the two path model。With the computation of absorb attenuation,we mainly consider the atmosphere absorb and rainfall attenuation。We choose the atmosphere model,DAH model and SAM model to compute。Afterward,according to the different geographic circumstance and project requirements,we reinforce the two path model and DAH model。With that,we can widen the application of two models。On the basis of this,the simulation scheme is designed,according to the actual project requirements。The simulation results illustrate the efficiency of the two path model in calculating the electric wave interference。The numerical values that get from the DAH mend model tallies with the numerical values that get from the DAH model。...
