Range and Angle Measurements based on Software Defined Radio Platform
In this paper, we develop a software defined radar system using NI-USRP 2920 which is programmed using LabVIEW platform. The system is capable of measuring distance and estimating the direction of arrival (DOA) of a specific source. For distance measurement, cross correlation is used to obtain the delay between the transmitted signal and the received one. Maximum radar resolution obtained is 9m with IQ sampling rate of 33. 33 M sample/sec. For angle measurement, MUSIC algorithm was used to estimate the DOA. The implementation of MUSIC algorithm was done in the software defined radio (SDR) platform.
