AbstractSynthetic aperture lidar is a new ultra-high resolution optical imaging instrument, but its reception field is very narrow which is subject to the "antenna theory". In this paper, the antenna efficiency theory is used to explain the antenna theory and the method of enlarging the field of view of the synthetic aperture laser radar. Then the increase range of the field angle of the three methods is deduced by heterodyne efficiency simulation. The simulation results show that the focal plane heterodyne detection optical path of the wide-beam local oscillator beam focal plane has the ability to improve the heterodyne efficiency of the edge field of view by reducing the heterodyne efficiency of the central field of view. The focal plane heterodyne detection optical path of the array detector requires the detector whose pixel size less than 3 times Airy spot radius covers the whole field of view, which can increase the maximum 1.83N times compared to the antenna theory. The effective field of the pupil plane heterodyne detection optical path of the array detector has nothing to do with the magnification of the telescope, the pupil diameter, the size of the detector, etc., which can be increased by N times as compared with the antenna theory. © 2019 SPIE.
