Among other quantities, we analyze the effects of the measurements noise, the tracking pass length and occurrence, the mission duration, the radio signal elevation and azimuth in the lander sky, the blackout periods, and the onboard power availability. The work is a comparative study, where we...
The work constructs the Gas kinetic solver (GKUA) to solve the Boltzmann model equation. Then the solver is respectively confirmed by NS, DSMC and experiments in typical conditions during reentry. Furthermore, the Maxwellian gas-surface interaction model is utilized to study the effects of reflec...
<div p-id="p-0001">A plastic panel and method of application for vehicle windows is disclosed. The plastic panel includes: a base layer; a weatherable film layer having a first and second surface, whe
This will result in serious system operation problems such as the communication blackout or radio blackout. Numerical modelling is one of the most widely used methods to investigate such complicated physical-chemical processes involving coupled magneto-hydrodynamics, heat transfer, dissociation, ionization...
In terms of the impact of the plasma sheath on radar, some scholars have conducted research on the multi-domain characteristics of radar signals. From the perspective of the time-frequency domain, a non-uniform plasma layering model is first established [3]. Then, the equivalent transmission lin...
During this process, we assume that the intermediate-frequency filter of the APD measurement is the same as that of a radio receiver, and the channel symbols of one coding block are modulated in the same way. The test bench employed in this simulation is presented in Figure 10, aiming to ...
