A New Receiver-Computer for Stacked-Beam Height-Finding Radars
Abstract
Although the target-elevation-angle receiver-computer for the AN/SPS-2 stacked-beam height-finding radar is satisfactory from an electrical standpoint, it is too large and complicated for installation on smaller ships and aircraft. A new receiver-computer system greatly reduced in complexity, size and weight is being developed for the AN/SPS-13 and the airborne surveillance radars. The center-of-gravity principle of computing and its implementation in the new receiver-computer are discussed in this report. The computing method is also compared with the one used in the SPS-2 system to show that the strong signal performance of the two systems will be essentially the same. Weak-signal performance of the new computer is also discussed, and it is shown that, although the basic computer is deficient in this respect, either of two modifications will bring its performance up approximately to that of the SPS-2. Three test-model computers are described along with modifications necessary in the log receivers for two of these computers. Preliminary test results obtained on these test-model computers bear out the conclusion that their performance, both on weak signals and on strong signals, will approximate the performance of the SPS-2.
