All rights reserved.Pulse radar is a device for emitting short pulse with high power and receiving echo signal from the target. At receiver side, pulse radar has an Automatic Gain Control (AGC) module to adjust receiver sensitivity and get the best amplitude level for the next process. The AGC type used in this research is HMC992LP5E. In previous research, gain settings used a classical closed loop AGC system. The disadvantage of this system is slow response of the AGC to change the input signal. As the result, it is difficult to distinguish between noise and target signal and differentiate amplitude level signal for different targets on radar system application. This paper explains the design of Automatic Gain Control (AGC) system using HMC992LP5E and fuzzy logic controller. The gain value of AGC is determined by input and output signal amplitude level of AGC and also the maximum range of radar targets. AGC gain value setting is provided by a certain voltage value at the pin VCTRL. VCTRL value is calculated by a 32-bit microcontroller using fuzzy logic algorithms. This controller will generate more dynamic value of AGC gain. The AGC output signal amplitude level can be determined based on fuzzy logic algorithms. So that, the target signal captured by the pulse radar receiver system will be more easily identified and can be used for other applications.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Automatic gain control,Fuzzy controller,HMC992LP5E,Microcontroller,Pulse radar[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.15676/ijeei.2016.8.1.5[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
