The usage of multi-input multi-output (MIMO) systems such as a MIMO radar allows the array elements to transmit different waveforms freely. This waveform diversity can lead to flexible transmit beampattern synthesis, which is useful in many applications such as radar/sonar and biomedical imaging. In the past literature most attention was paid to receive beampattern design due to the stringent constraints...

A robot vision system is developed based on an intelligent image gathering card that contains an FPGA (Field Programmable Gate Array) and a DSP (Digital Signal Processor) as main calculators. Two real-time visual modules are developed through the cooperation of hardware logics on FPGA and software on DSP. First, with edge images extracted by the FPGA, a highly efficient algorithm is designed to extract...
Phased array used in spacecraft must be lightweight, high efficiency, high integration and low profile, nonlinear active antenna array which have these merits is suitable for the case. This paper studies a two-beam scanning system of nonlinear active array based on injection-locking technique. Firstly, the article reviews the theory of injection-locking technique, then we analyze basic method of differential...
