Two-Dimensional DOA Estimation of Broadband Chirp Signals with a Single Electromagnetic Vector Sensor Using Fractional Fourier Filtering

This paper proposes a new Azimuth-elevation angle estimation algorithm for multiple broadband chirp signals using a single electromagnetic vector sensor.Two distinct signal scenarios are considered.For multiple signals with same power,the proposed algorithm applies the fractional Fourier transform(FrFT) to estimate the steering vectors of electromagnetic vector sensors,and then to obtain azimuth-e…
