Motivated by the development of MIMO communication, Multiple-Input Multiple-Output (MIMO) radar has drawn considerable attention. Currently, most articles about MIMO Radar analysis focus on angle diversity, the article investigates principal component analysis used in MIMO Radar detection, further studies the performance of transformation of logarithm as its improvement. The simulation results indicates...
High-speed T/R converter is developed in this paper by using the combination of the circulator, the limiter and the RF switch technology. The super low noise receiving technology is realized through reducing the transmission loss and improving the gain of LNA. Experiments have proved that the T/R component's power tolerance in this paper is more than 100 W, and that the blind distance caused by it...
First of all, the detection theory of the instantaneous polarization radar is introduced. The overall structure of dual-channel circuit has been designed. The principle part of RF system consists of antenna arrays and the dual-channel receiving and transmitting circuit. Si4133 chip used as the core design of the high stability, fully coherent frequency synthesizer as instantaneous polarization radar's...
To simulate synthetic aperture radar (SAR) raw data of extended scenes in the presence of arbitrary trajectory deviations, an efficient simulation scheme based on parallel computation in hybrid domain is proposed. We firstly present a novel target-to-antenna distance model which takes the three-dimensional components of the trajectory deviations into consideration. Then a general and compact hybrid...
