Video Mixing and Minimum Detectable Signal in the SPS-2 Radar
Abstract
The parameters of the proposed SPS-2 long range search radar were simulated, and the effect on the minimum detectable signal of mixing two video channels, representing adjacent elevation channels of the system, was determined for equal signals in the two channels and for signal in one channel only. In the former case the minimum detectable signal was 1.6 db lower in the latter case 1.6 db higher than for a single unmixed channel. The minimum detectable receiver signal-to-noise ration was found to be 7.4 db. The maximum free-space range of the system, with the stated parameters and for a target of one square meter cross-section, was calculated to be 318 nautical miles.
