PURPOSE:To accurately calculate the Doppler center frequency of the image of synthetic aperture radar (SAR). CONSTITUTION:A means applying fast Fourier transform to the raw data of SAR in an azimuth direction to form a waveform transformed to the spectrum region in a range line and a means ...
Bi/multi-radar using cooperative or non-cooperative transmitters has attracted much attention in the international community. This paper analyzes performance of the locating a moving target from corrupted Doppler frequency measurements obtained by a single receiver with two cooperative or non-cooperative tr...
the target. When the target moves with a constant velocity, the carrier frequency of the returned signal will be shifted. This is known as the Doppler effect [1]. For a mono-static radar where the transmitter and the receiver are at the same location, the roundtrip distance traveled by ...
The micro-Doppler(m-D) effect provides a new approach for auto radar target recognition.The frequency-stepped chirp signal makes the fine m-D signatures extraction of target possible because of its high range-resolution capability.Based on the expatiation of the imaging principle of the frequency...

Micro-Doppler effect in radar: Phenomenon, model, and simulation study When, in addition to the constant Doppler frequency shift induced by the bulk motion of a radar target, the target or any structure on the target undergoes... Chen, V.C.,F Li,Ho, S.-S.,... - 《IEEE Transactions...
Define Doppler. Doppler synonyms, Doppler pronunciation, Doppler translation, English dictionary definition of Doppler. Noun 1. Doppler - Austrian physicist famous for his discovery of the Doppler effect Christian Johann Doppler Based on WordNet 3.0, Far
We investigate the algorithm of direction and Doppler frequency estimation for bistatic multiple-input multiple-output (MIMO) radar in spatial colored noise. A novel method of joint estimation of direction and Doppler frequency in spatial colored noise based on propagator method (PM) for bistatic MIMO...
The performance of mean-frequency estimators for Doppler radar and lidar measurements of winds is presented in terms of two basic parameters: Phi, the ratio of the average signal energy per estimate to the spectral noise level; and Omega, which is proportional to the number of independent samples...
Micro-Doppler induced by mechanical vibration or rotation of structures in a radar target is potentially useful for target detection, classification and recognition. While the Doppler frequency induced by the target body is constant, the micro-Doppler due to vibrating or rotating structures of the tar...
