Abstract
- In this article, we present the analysis of the electronic circuit of the hardware architecture allowing to detect the pulses with great precision the PTAIs (time of arrival of the pulses) as well as their widths within CGA of the radar system. A system that is used to control a variable gain attenuator and that sends pulse measurements to a computer recognition device. It is thanks to the CGA that the recognition system will be able to process the signal optimally. It seems imperative to us to proceed with the study of the digital process of detection of radar signals in the real-time air security of N’djili airport to present the state of the art on radars. This state of the art consists in presenting in turn a brief history of the radar, the different radar architectures, the different types of radars, the characteristics of the radio channel and the diversity in telecommunications. The aim of this article is to improve. However, as the waveforms of the return signals are distorted by system noise, errors are made in their detection and estimation. Calculations of time of arrival and widths that minimize pulse errors during radar detection are still complex issues to be solved
