Recently, intelligent methods, including fuzzy inference, robust control, evolutionary computation, swarm intelligence, and ant colony, play an important role in the development of smart sensor array technology, which brings together additional interdisciplinary research skills in the development of innovative antijam devices, microelectromechanical systems, aerospace, laser, optics, wireless communications, and multiple signal reception processor for modern phased array applications. One of the main advantages of using phased array processing along with an array of sensors is a smaller footprint. The problems associated with array processing include the number ofsources used, their direction of arrivals, sensor placement, sensor structure, and their signal waveforms. Generally, satisfactory results can be obtained by employing conventional intelligent algorithms on smart sensor array applications.

However, smart antenna array technologies demand to be more robust, have more precision, be costly, and be more efficient computation complexity; therefore, it is worthy of our effort to develop hybrid intelligent algorithms and mechanical solutions capable of improving the performance of existing sensor array technology. The current research orients towards low-cost and simple methods to overcome the effect of uncertainties on the whole array system. In particular, after the future array system is miniaturization, the design method of circuit protection within array system is inevitably a crucial issue. Recent research illustrates that hybrid intelligent methods which are integrated with some standard ones can help achieve a better performance for particular phased arrays applications. It was indicated that hybrid intelligent processing can generally bring a more convincing solution for a particular micro/nanoelectronics array...
