Pulsar signal detector based on single event effect

Abstract

The invention discloses a pulsar signal detector based on single event effect, relating to the technical field of data processing and solving the problems of support defect of low-pressure high-vacuum and low-temperature environment and overlarge detection area of the traditional detector. The pulsar signal detector comprises a register unit array comprising M+1 register units and an adder array comprising M adders, output ends of the first register unit and the second register unit are respectively connected with the first input end and the second input end of the first adder, the output end of the first adder is connected with the first input end of the second adder, the output end of the third register unit is connected with the second input end of the second adder, the carry output end of the first adder is connected with the low-level carry input end of the second adder, by suck analogy, the output end of the mth adder is connected with the first input end of the (m+1)th adder, the output end of the (m+2)th register unit is connected with the second input end of the (m+1)th adder, and the carry output end of the mth adder is connected with the low-level carry input end of the (m+1)th adder, wherein m is more than 1 and less than M; and the output end of the Mth adder is used as a final result output end. The invention is applied to detecting pulsar signals navigated by spacecrafts.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a pulsar signal detector applied to spacecraft navigation applications. Background technique [0002] The single event upset effect is mainly caused by high-energy protons and heavy ions in the space radiation environment, and the single event upset that mainly occurs in memory devices and logic circuits occurs most frequently. The single event flip is the charge generated around the heavy ion movement track that is collected by the sensitive electrode, forming a transient current, triggering the logic circuit, and causing the logic state to flip. This phenomenon was first discovered on microprocessors and memory cells operating in spacecraft and satellites, where a single event causes certain bits of the processor or memory cells to flip 0-1. High-energy particles or other particles with considerable energy are injected into the integrated circuit. Generally, high-energ...
