Opportunistic radar appeared recently as a solution for opening more spectrum for future radar applications. Opportunistic radar harnesses spectrum opportunities and transmits without causing intermittent interference to incumbent applications. We propose a multiple-input multiple-output (MIMO) radar pre-coder design that enables spectrum sharing with long-term-evolution (LTE) base stations. In the proposed design, pre-coder settings are configured continuously using a steepest descent (SD) approach given certain interference constraints. The presented designs have lower computational complexity compared to other designs proposed in literature. We construct the SD based MIMO radar and analyze its performance.
