It is then seen that the signal estimate remains constant with random input frequency regardless of frequency redundancy whereas noise with frequency redundancy is decreased in accordance with a frequency sampling efficiency gain in Table I. This sampling efficiency is (FcK))/(F(w)) = (F(K))/(l.53). The effective number of integration samples with unity… (More)
s This article recounts the development of radar signal processing at Lincoln Laboratory. The Laboratory's significant efforts in this field were initially driven by the need to provide detected and processed signals for air and ballistic missile defense systems. The first processing work was on the Semi-Automatic Ground Environment (SAGE) air-defense… (More)
1 The HPCchallenge benchmark suite has been released by the DARPA HPCS program to help define the performance boundaries of future Petascale computing systems. The suite is composed of several well known computational kernels (STREAM, Top500, FFT, and RandomAccess) that span high and low spatial and temporal locality. These kernels also encompass key… (More)
