At present, the integrated radar and communication (RadCom) system has attracted much attention. It has several advantages such as power consumption, reducing system size, weight,...etc. This paper proposes a power allocation strategy
for the RadCom system in signal-dependent clutter, where both systems use the Orthogonal Frequency Division Multiplexing (OFDM) waveform. The convex optimization problem is formulated and solved analytically by using the Karush-Kuhn-Tuckers (KKT) optimality conditions. The proposed strategy minimizes
the total transmitted power while fulfilling the two systems requirements i.e., Signal-to-Clutter-plus-Noise Ratio (SCNR) for the target detection performance and Data Information Rate (DIR) for the communication system performance. Finally, the simulation results are presented to verify the effectiveness of the
proposed power allocation strategy.
