The radar altimeter auto test system and the original test method were introduced, and the disadvantage that this method is inefficient was brought forward. The method of radar altimeter sensitivity testing using dichotomy method, which was used to improve the efficiency of radar altimeter sensitivity testing, was proposed. The test result and test flow were presented. Using this method a few stimulating and output voltage data were used to fitting the relation function, which was used to calculate the begin stimulate voltage, and then adjust the stimulate voltage with small voltage to test alarm signal precisely. According to the test result, the conclusion can be reached that the optimized method can be much more efficient while the testing precise of the sensitivity is the same.
