No, absolutly NOT, Microwave Ovens are NOT pusled, they are CW, and continious. It is AVERAGE Power that fries you, not Peak Pulse Power. See, this is what you seem not to understand, about the technology that is being discussed. You don't seem to have a grasp of how the technolgy works. I only know the power rating. I am not sure arcing incidents are that rare as I have met a couple of people who claim to have seen it happen. and I have meet a lot of people that claim to have seen and been kidnapped by aliens, too...... If a hammer drops on your foot and then rests there for 20 minutes, is it the pulse or the average force to look out for. not analogous, at all, and just shows that yoiu don't undertand the technology that you talking about. My radar... Peak Power Output: 7.5 KW nominal, 6.0 KW minimum Output Frequency: 9375 Mhz (X-Band) Most likely using a 2J42 Magnitron or equivilent.... I think it does 160 pulses per second. that seems a bit low, should be in the 500 to 750 range, but ok.. and the Pulse Width, which you don't cite, is the determining factor in calculating the Average Power of the RF Energy emitted from the device. Typical Pulse Widths would be in the .1 to 1 microsecond range for this type of radar. So lets take 1 microsecond. 1 * 160 = 160 microseconds total ON time out of 1000000 microsends/second 160.0/1000000 *7500 Watts Peak Pulse Power = 1.2 Watts Average Power Now understand that RF Energy is nonIonizing radiation and therefore interacts with biologics as HEAT. Now just how much heat will be transfered to you from a 1.2 Watt light bulb held in your hand, assuming that you get 100% capture of that power into your hand, and considering that if your standing out in front of the antenna even at one foot, the Inverse Square Law still applies? You would be willing to take the full brunt of that one foot away? I will be back at the airport this afternoon and ask for someone to hold thier head up to the radome. I never went to radar school. that is obvious.... I'll take your word for it, but I won't volunteer! Me |
