Title:
METHOD FOR SHARING RADIO FREQUENCY IN TIME-MULTIPLEX MODULATION
Document Type and Number:
Japanese Patent JP2003121538
Kind Code:
A
Abstract:
To provide a method for allowing a radio frequency for sharing time- multiplex modulation for efficiently, using a radar resource and at the same time, obtaining the fully satisfactory maximum efficiency.
The apparatus is used for a plurality of base radars for sharing a frequency due to GPS time-multiplex modulation. The apparatus comprises a GPS receiver 2, stabilizer 5, clock generator 4, microprocessor 7, memory chip 8, signal synthesizer 6, and computer 10. The GPS receiver 2 extracts time information from GPS signals. The stabilizer 5 controls radar functions to time. Then, the microprocessor 7 performs multiple modulation processing on radar signals.
