Vibrating Antenna Doppler Radar
2020 17th European Radar Conference (EuRAD), 2021This paper presents a new method of gaining spatial resolution in continuous wave (CW) Doppler radars by using a vibrating antenna. Resolution of direction finding, though conventionally controlled through beam steering or other circuitry, is decoupled from the antenna and front-end circuitry by vibrating the antenna in a controlled fashion.

The Doppler Radar Signals Processing
2019 9th International Conference on Advanced Computer Information Technologies (ACIT), 2019A spectral method for processing Doppler radar signals is proposed. Discrete fast Fourier transform is commonly used in communications (areas) in both mobile phone processes and devices for compressing audio and video to transmit via telecommunications networks. For now the relevant objective is to increase the efficiency of these systems.

Publisher Summary This chapter throws light on the pulse Doppler radar. Doppler shifts are a key part of the detection and tracking of objects. For this reason, nearly all radar systems incorporate Doppler processing. It has been working since the ground returns are at the same range as the vehicle, the difference in velocity is the means of ...
