Narrowband Direction of Arrival Estimation for Antenna Arrays
Preparing the books to read every day is enjoyable for many people. However, there are still many people who also don't like reading. This is a problem. But, when you can support others to start reading, it will be better. One of the books that can be recommended for new readers is narrowband direction of arrival estimation for antenna arrays narrowband direction of arrival estimation for anten...
متن کاملHigh Resolution Techniques for Direction of Arrival Estimation of GPR Signals
In this paper, the Direction of Arrival (DOA) estimation is implemented using a steppedfrequency ground penetrating radar data for antipersonal landmines detection. Different experiments for different anti-personal landmines for different depths have been achieved. The techniques used in this paper are high-resolution techniques such as Multiple Signal Classification (MUSIC), and EigenVector (E...
متن کاملDirection of Arrival Estimation of RF Signals Using Five-Port Technology and High Resolution Method
This paper presents a system based on five-port demodulator which measures DoA (directions-of-arrival) of radio frequency signals received on an antenna array in the azimuth plane. The receiver operating at 2.4 GHz is composed of four five-port demodulators connected to a ULA (uniform linear array) of four patch antennas. The DoA is estimated by measuring the phase difference of signals picked ...
متن کاملDirection of Arrival Estimation
We have seen that there is a one-to-one relationship between the direction of a signal and the associated received steering vector. It should therefore be possible to invert the relationship and estimate the direction of a signal from the received signals. An antenna array therefore should be able to provide for direction of arrival estimation. We have also seen that there is a Fourier relation...
متن کاملDirection of Arrival Estimation
Array Signal Processing (ASP) is a relatively new technique in Digital Signal Processing (DSP) with many potential applications in communication and speech processing. Direction of arrival (DOA) can be estimated using different techniques evolved with ASP. It is observed that subspace method provides superior performance in resolving closely spaced sources.
