Abstract

While meteorologists can obtain much useful information by using radar in a qualitative manner, great benefit can be derived by obtaining quantitative measurements. However, these measurements have been found, in general, to be below values calculated from radar theory by a factor of between two and five, and there has been no satisfactory explanation for this discrepancy. In this paper, the radar equation for a meteorological target is derived, particular attention being devoted to the effect of the shape of the main lobe of the beam, and of the radiation outside it. It is shown that previous theoretical expressions for both the gain and the echoing volume have been too large, and hence that previous equations overestimated the received power. The present equation gives good agreement with all the experimental data.

## Abstract It is usual to use finite‐difference methods in carrying out the time integration of the equations of motion as adapted to the prediction of the large‐scale atmospheric pattern, and this implies a choice of the mesh length and time increment to be used.

A radar equation which can be applied to any bistatic acoustic sounder is derived. The equation reduces to the expression normally used for the special case of the monostatic sounder. Numerical results using this equation are given for specific acoustic sounders, including the relative contributions
