Compared with sequential single‐input–multiple‐output array, a novel design method of high‐efficiency sparse array is proposed to achieve the similar azimuth resolution and lower grating‐lobe level. Theoretical analysis and numerical experiments demonstrate that the designed array is irredundant and the efficiency is increased. The work can benefit the development of high‐resolution imaging and low‐cost ultra‐wideband radar.
