Design of Phase Coded Sequences for MIMO Radar Systems
Abstract: MIMO radar technology is emerging trend in the radar systems and researchers are interested to explore this technology. Phased array radars show single waveform radiated in one direction where has MIMO antennas can radiate in different directions and locate multiple targets with better resolution. To design waveform for MIMO radar, every transmitted waveform must orthogonal all corresponding waveform. Many binary orthogonal sequences, i.e., orthogonal with respect to frequency or phase …

Orthogonal Thirty-Two Phase Sequence Sets Design
Abstract: In using orthogonal signals, a multi-input, multi-output (MIMO) radar system and a spread spectrum communication system can improve operating efficiency. The usage of polyphase coded signals as pulse compression sequences sets is a superior alternative. The Modified Genetic Algorithm (MGA) is utilized as a global optimization strategy to create thirty-two phase sequence sets in this work. Design orthogonal thirty-two phase sequence sets with an impulse-like Autocorrelation Function (ACF) and a …

A Review on Wi-Vi Technology
Abstract: Wi-Vi is a new emerging technology that captures moving objects behind a wall or obstacle. Previous attempts used array of spaced antennas to track the moving objects through walls. This would be very expensive and bulky. So, in its place Wi-Vi is used which uses only one receiver. Wi-Vi technology is similar to radar and sonar imaging. But Wi-Vi uses very low power Wi-Fi signals for the transmission. The Wi-Fi …
