Two formulations for determining the characteristics of an unknown source of acoustic waves using the measurement of its field at its near zone are presented. The measurement in both cases is to be performed on a spherical scan surface which encapsulates the source. The first is for an ideal probe which measures the field at its location. The knowledge of(More)
This study which was conducted as a Master's thesis, is a radar system working at X band. In this system, a 2 Watt continuous electromagnetic wave which is modulated with frequency ramp of 30 MHz bandwidth is generated and radiated through TX antenna. The scattered signal from the hydrometeors is multiplied with the transmitted one and beat signal is(More)
This paper investigates the effects of multipath channel on angle of arrival (AOA) estimation with cross correlation time difference of arrival (TDOA) method. System model of a direction finding system that uses TDOA cross correlation method is presented. Effects of delay spread and average channel power delay profile on AOA estimation performance are(More)
This study aims to experimentally investigate the feasibility of discriminating human motions with the help of micro-Doppler features by using radar. In the first phase of the work, the synthetic data is generated through the human walking simulator by V. Chen and different time-frequency transformations are applied on the data. In the following phase,(More)
