PROJECT TITLE :
Sparse Sequential Single-Input–Multiple-Output Array Design for Ultra-Wideband Radar
This letter investigates the array design ways of the sequential single-input-multiple-output (SSIMO) array. Antennas of SSIMO array are both transmitters and receivers, and when one antenna transmits, others receive. Compared with the widely used multiple-input-multiple-output (MIMO) array, SSIMO array has the similar azimuth resolution however lower grating lobe level (GLL). As a general rule, periodic and irredundant (PIR) ultra-wideband one-means array provides a means that of improving the azimuth resolution and lowering the GLL. Primarily based on this principle, we have a tendency to 1st propose the design technique for the SSIMO array with four antennas. However, if the amount of antennas exceeds four, the effective array of the SSIMO array cannot be PIR. However we tend to have successfully proposed a novel design method to house this downside. The simulation results and design example verify the correctness and effectiveness of the proposed method.
