The use of GNU radio which is frequently implemented in software define radio (SDR) is to simplify the development especially in the modulation process of FMCW radar. The beat frequency filter for LFM-CW radar with components for distances of Om and 3m is applied for the realization of GNU software into radio and applied on the USRP. The signal level at receiver will change inline with the variation of target distance. If the target range is further the signal level shrinks. Signal receiver particularly vulnerable to interference noise when the distance is far. LFM-CW radar waves are generated using GNU Radio and USRP already meets the specifications. The radar is implemented in GNU Radio is also capable of detecting one or three targets at varying distances. The difference in the frequency spectrum owned chart on GNU Radio and MATLAB® occurs because the graph GNU radio frequency spectrum, frequency components are taken only positive frequency components, while the negative frequency components are ignored.[/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]Frequency components,GNU radio,Linear FMCW,Linear frequency modulated continuous wave,Linear frequency-modulated continuous-wave radars,Positive frequencies,Software define radios,USRP[/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]GNU radio,Linear FMCW,Radar,USRP[/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/10.1109/ICWT.2015.7449265[/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]
