摘要： A radar system comprises a transmitter antenna configured to transmit a radio frequency (RF) signal, a first receiver antenna, and a second receiver antenna. Each of the first and second receiver antennas are configured to receive a reflection of the RF signal, wherein the first and second receiver antennas are synchronized and separated by a vertical distance. The radar system also comprises radar processing circuitry configured to control transmission of the RF signal from the transmitter antenna and to determine an elevation of an object reflecting the RF signal based on the phase difference between the reflected RF signal received by the first receiver antenna and the reflected RF signal received by the second receiver antenna; wherein the transmit antenna, first receiver antenna, and second receiver antenna are operable to continuously rotate 360 degrees along an azimuth angle without rotating along an elevation angle.

摘要： An RFID tag has a memory, an RF transceiver that supports long range RF communications with a long range reader, and an interface that supports short range communications with a short range reader over a secure link. The RF transceiver can be used to transmit an ID stored in the memory of the tag to a long range reader, and the interface can be used to transmit sensitive history information to a short range reader over the secure link. The ID uniquely identifies an article to which the tag is attached, and the history information provides environmental data, and/or maintenance data, and/or shipping data, and/or inventory data, and/or production data, etc. about the article.
