Design and Simulation a New Unique-Slit Reticle for Pulsed Infrared Seekers

Taking the rubbish in the campus of Shanghai Electric Power University as the test object, the single-factor and three-factor five-level orthogonal test design methods were adopted to conduct an experimental study on the cleaning performance of the road cleaner cleaning system and obtain the optimal combination. The mathematical models of the three main factors of driving speed, disc brush speed and roller brush speed and the road sweep rate were established. The influence of each influencing factor and its interaction on the road sweep rate was analyzed, and parameters optimization and test verification were performed. The best combination was found to be a running speed cleaning speed of 5.27 km•h-1 , a disk brush speed of 106.85 r•min-1 , a roller brush speed of 159.86 r•min-1 , and a road cleaning rate of 92.81%. After the test is verified, it is basically consistent with the theoretical optimization results.

This paper presents an approach to seeker-azimuth determination using the gyro rotor and optoelectronic sensors. In the proposed method, the gyro rotor is designed with a set of black and white right spherical triangle patterns on its surface. Two pairs of optoelectronic sensors are located symmetrically around the gyro rotor. When there is an azimuth, the stripe width covering the black and white patterns changes. The optoelectronic sensors then capture the reflected optical signals from the different black and white pattern stripes on the gyro rotor and produce the duty ratio signal. The functional relationship between the measured duty ratio and the azimuth information is numerically derived, and, based on this relationship, the azimuth is determined from the measured duty ratio. Experimental results show that the proposed approach produces a large azimuth range and high measurement accuracy with the linearity error of less than 0.005.
