abstract = "A high angle and range resolution imaging method using a double-ping frequency diverse multiple-input multiple-output (MIMO) sonar is proposed. The proposed MIMO sonar is composed of a uniform linear array (ULA) and two transmitting elements located at the two ends of the receiving ULA. The interelement spacing of the two transmitting elements is equal to the produce of the inter-element spacing and the element number of the receiving ULA. We show that such array configuration is able to ensure a high angle resolution without increasing the array physical size. At the same time we use a pair of frequency diverse linear frequency modulation (FD-LFM) pulses to achieve a high range resolution. Based on the array configuration and the transmitting waveforms, we give the double-ping signal transmitting mode and the echo processing procedure. Via numerical simulations we show that the proposed double-ping MIMO sonar imaging method can improve the angle and range resolutions simultaneously.",
