Research on Rocket Sled Full-range Velocity Measurement Technology Based on Optoelectronic Tags
Rocket sled testing plays a crucial role in weapon development and performance evaluation.However,existing meth-ods have some shortcomings for rocket sled velocity measurement.To address the challenge of full-range velocity measurement in rocket sled testing,an optoelectronic tag-based method for full-range velocity measurement is proposed.Establish the detection model for optoelectronic tags,investigate their directional reflection characteristics,analyze and simulate the signal variation process of the sensor during dynamic measurements,select the photoelectric detection device based on the frequency characteristics of the signal,build the hardware measurement circuits,and validate the system.Experimental results demonstrate that the detect distance of the sensor to the photoelectric tags reaches up to 40 cm,and the velocity measurement range meets the requirements for rocket sled tes-ting at weapon proving grounds.Compared to traditional methods,the optoelectronic tag method has lower cost and broader applica-bility in full-range velocity measurement for rocket sleds.
