Solid state development of a C band pulse altimeter

In this paper parameters of an old technology altimeter are discussed and then after deriving measure of quality factor (height measurement accuracy), suitable solutions for improving the technology, decreasing its peak power (from 62.5 w to10.9 w) so improving LPI characteristics and maintaining its performance quality are presented. In this altimeter, by interchanging microwave old devices such as TWT with solid state devices, quality and LPI characteristics of these systems are increased in spite of reduction of their size and cost. So access to systematic parameters of a pulse altimeter with low power, smaller weight and dimensions, higher security and defence capabilities is possible easily. In this way, it is of special importance to trade off the parameters and select the optimum solution.
