| Abstract: |
| According to the nonlinear re-radiation characteristic of semiconductor
PN node, the nonlinear node detection system for semiconductor junction targets
based on second harmonic reception is designed.System simulation and experiment
results show that the system can detect well the node of no
nlinear component with gain high enough for signal detection. |
