Abstract:

A limited design approval test was made of a low level radar altimeter, designated ANAPN- 155. The altimeter, a conventional FM-CW type with altitude coverage from 0 to 5000 ft, intended for use in the F-110A aircraft, employs a solid state modulator. Size, weight, and form factors of the RCA unit are less suitable than other models under consideration. Application of the units as an altitude retention device in helicopters is precluded by excessive step error. In addition to solid state modulators, the next generation of radar altimeters should incorporate a solid state transmitter to eliminate a second weak design area in present altimeters. Author
