Abstract

The invention discloses a spaceborne composite data fusion method based on pulse per second, which is applied to a spaceborne composite radar and aims to perform data fusion output on an optical angle, a microwave angle and a mechanism angle of the composite radar. The method specifically comprises the following steps: providing a spaceborne composite data fusion method based on pulse per second, carrying out data linear interpolation fusion in a pulse per second calibration mode, and outputting final target angle information. The method provided by the invention is easy to implement, has small influence on the scale, complexity and robustness of software, does not influence program design, coding and debugging, and can select the criterion of pulse per second timing according to the actual situation.

Description

technical field

[0001] The invention relates to the technical field of satellite data fusion application, in particular to a method for fusion of satellite-borne composite data based on second pulses. Background technique

[0002] Microwave radar technology uses the phase-amplitude relationship between the transmitted electromagnetic wave and the received microwave to measure and track the distance and speed of the target. The existing microwave radar technology is very mature. However, due to the limitations of the measurement system and hardware, the angle measurement accuracy of spaceborne microwave radar cannot reach a very high level.

[0003] The optical radar technology uses an optical camera to image the target area, and extracts the angle information of the target from the optical image. Due to the influence of background celestial bodies, it is difficult for spaceborne optical radar to extract targets from the background celestial bodies, and the working distance ...
