Optimization of Target Detection in Spectrum Sharing Scenario Assuming Distance as Specification Criteria

Abstract

The demand for spectrum usage is increased which requires new spectrum allotments. For the coexistence of wireless system with the radar systems a dynamic allocation of spectrum method is proposed along with the noise power the communication system power is considered as interference power to the radar system. The communication power effect on radar system as a function of distance is analysed .A multiple input multiple output radar system and MIMO wireless communication system with K base stations are considered. The communication system transmit covariance matrix is designed based on the radar sampling scheme to reduce the effective interference power (EIP) for radar receiver by certain average capacity and transmit power maintained for communication system
