Abstract

At this time, the development of radar technology has experienced quite rapid developments. The use of radar can now be used to detect body movement using sign language and represent it in the form of a signal so that it can be sent via telecommunications networks to other places. However, in telecommunications networks there are limitations regarding the amount of information that can be sent so that the information must go through several process stages such as compression of information data so that a reconstruction process is needed to restore the signal. In this research, the author used MatLab software to process the information data signals using the OMP method which was then classified using the CNN method. Tests were carried out using Doppler radar with conditions blocked by walls and without blocked walls and at varying distances ranging from 1m, 2m, 3m, 4m, 5m, and 6m to obtain information data signals from sign language movements which were then processed in MatLab software. From the test results in this research, it was found that the performance parameters when processing using the OMP method in conditions without obstructions had good results with an average SNR value of 34 dB and an average MSE value of 0.561%. Furthermore, when classifying using the CNN method, an MSE value of 13.89% was obtained or a classification success rate of 86.11%.
