Abstract: Synthetic bandwidth waveform yields high range resolution with equivalent wide bandwidth by applying hopped frequency and coherent processing between different pulses. However, when a moving target is concerned, the quality of the high range resolution profile would degrade seriously because of the Doppler effect in the linear and quadratic phase items of the echo signal, which is caused by radial velocity of the target. Generally, radar needs to emit another waveform with narrow bandwidth to help measure the target speed but at a cost of added hardware resources. In this paper, a frequency hopped synthetic bandwidth waveform design and processing algorithm for self-speed measurement is proposed. Speed of the target can be effectively measured in low SNR environment, which is superior to many existing methods. In addition, the hopped frequency can be flexibly designed by changing several parameters, which presents good anti-interference performance.
