Onboard DME Jitter Frequency Signal Generator Design and Implementation Based on FPGA
摘要
Abstract
The Distance Measuring Equipment is one of the essential onboard navigation systems. Identification of reply pulse,which adopts a strobe frequency principle,is the kernel of DME distance measuring. The jitter frequency signal generator is the most important circuit to implement strobe frequency. Based on FPGA,an onboard DME jitter frequency signal generator circuit is designed and implemented. The circuit consists of a random number generator, variable frequency divider,etcetera. Testing shows the circuit operates with stable performance and high reliability.关键词
