We first find the spectral resolution of the low-frequency gravitational radiation emitted by a system of colliding particles. This is done by applying Fourier analysis to Landau and Lifshitz's formula for the gravitational radiation intensity. The result is in accord with that recently obtained by Weinberg through quantum-gravidynamical methods, which predicts 6×1014 erg/sec for the solar gravitational radiation power. We then find the total gravitational radiation of the same scattering process for all frequencies and without resolution into a Fourier integral. The calculation is free from any cutoff process which is needed for the low-frequency power, and the result is one order of magnitude larger than the low-frequency power when applied to the solar system.
