| Abstract | In October 1971, TSC was asigned the task of assessing the current ASDE-2-maintenance problems.- After studying the available statistics, obtained from various airports, it was quickly concluded that the preponderance of ASDE-2 radar failures originated in the modulator-transmitter section where the low mean time between failures as controlled by the following inter-related factors: 1) An undersized hydrogen thyratron driver for the power amplifier; 2) An inadequate trigger pulse amplifier output; 3) Poor operating conditions for the power amplifier tubes. The report analyzes these and other engineering inadaquacies and then describes in detail the modification of one channel of an ASDE radar at TSC. To date the system has been operating for several months without any modulator failures. This is nearly fifty times longer than previous mean time between failures. |
