Abstract: |
|||
| Based on pulse method radar ranging, the invention improves former method for measuring time difference, discloses system framework of pulse radar and executive plan based on equivalent sampling method. Smart combining equivalent sampling with pulse radar, the makes improvement further based on issues encountered in practice. Using minor frequency difference between transmitting and receiving signals, the invention realizes equivalent signal sampling for echo signal of pulse radar. Thus, widening original short time difference, the invention realizes measuring short time difference and distance of electromagnetic wave propagation. | |||
