Aim at a two paths model of reentry telemetry channel and a three wave beams wait-receiving system, we have used the function of antenna gain pattern to educe the power s mathematics expression of the received signal after the warhead coming out the blackout.

In order to improve the transmited rate via compensating the channel's attenuations, it is significant to research the the characteristics of reentry telemetry channel.

Aimed at PCM/FM reentry remote sensing systems existed in multipath-Induced, the characteristic of amplitude, phase, group delay of the two-path model is analyzed based on presenting some typical theoretical models of reentry remote sensing transmission channel.

The Pulse Code Modulation/Frequency Modulation (PCM/FM) is widely used in most Reentry Remote Sensing (RRS) system at the present time in our country.
