ABSTRACT:
A low cost telemetry receiving system for use with an atmospheric sounding device includes an antenna configuration mounted on an azimuthally rotatable platform. The antennas have an asymmetrically shaped receiving beam having a narrow azimuth and wide elevation. The wide elevation is fixed due to a first antenna being oriented zenithally, and a second antenna being oriented horizonally. Rotating an azimuthally rotatable platform facilitates full canopy coverage for receiving telemetry. Determining when to reposition the rotatable platform is accomplished by sensing the strength of telemetry signal by rapidly sequencing the receiving beam so that it sweeps azimuthally within the narrow azimuthal view of the antenna. The platform rotates in the direction the signal is strongest. Because the antenna is a receive only antenna with one mechanical part, and the antenna is constructed with microstrip patch array technology, the overall antenna system is inexpensive and highly reliable for use in receiving telemetry from wandering atmospheric sounding devices.
