The 3 waveforms used for the investigation as FM chirp are sinusoidal, triangular, and sawtooth waveforms. The analysis is performed by use of GNU radio referred as an open source software-define-radio project. There are 2 methods employed for the detection process; the first is real-condition simulation method and the second is USRP-based implementation method. In the analysis, some targets in different ranges are characterized using both methods to determine the accuracy of target range. By using FFT (Fast Fourier Transform) function from Matlab® to obtain the result in frequency domain, both methods show that the triangular waveform has the highest average accuracy, i.e. 95.73% for the 1st method and 99.75% for the 2nd method. The sawtooth waveform has the lower average accuracy than the triangular, i.e. 94.93 for the 1st method and 98.33% for the 2nd method, whilst the sinusoidal waveform has the lowest average accuracy, i.e. 92.60% for the 1st method and 98.59% for the 2nd method. From the result, it shows that the USRP-based implementation method has better average accuracy than the real-condition simulation method.[/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]FFT (fast Fourier transform),FM chirp,Frequency modulated continuous wave radars,Frequency-modulated continuous waves,GNU radio,Multiple-target detections,Sinusoidal waveforms,Triangular waveform[/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]FM chirp,frequency modulated continuous wave (FMCW),GNU radio,multiple target detection[/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/IC3INA.2014.7042611[/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]
