- Abstract
- As the damage caused by high power electromagnetic (HPEM) is getting worse, it is necessary to analyze the damage and to study of shielding it. The coupling of HPEM to electronic devices is divided into two ways; (1) Front-door coupling and (2) Back-door coupling [1]. The former is inflow of HPEM pulse through an intended path and the latter is inflow through an unintended path. Since HPEM pulse flow in through an intended path in former case, HPEM pulse with higher power is induced and cause bigger damage to electronic devices. Because of these problems, it is necessary to study the damage and shield of RF systems affected by HPEM pulse. In this paper, damage modeling on the radar affected by HPEM pulse is shown. The damage of a radar falls into four types: (1) Deception, (2) Jamming, (3) Upset and (4) Burnout [2]. The process of damaged radar, which is sorted by each damage levels, is simulated by circuit elements. Particularly on this paper, it is examined the low noise amplifier (LNA) in a radar system. Because it operates in lower power level than HPEM pulse, LNA burns out even in the low input power circumstances. This circuit model is simulated by PSIM. Through the circuit models, which non-linear phenomena and damage of LNA, was expressed through the steps and it is expected to help studies which are to model the damage of a radar and to shield a radar affected by HPEM pulse.
