A method and device for deriving and displaying advanced TCAS information. 0, Bomya et al., 340/573.1; US-6424149, 20020700, Takahashi ing a plurality of antennas, a plurality of mixers for converting signals sent from the antennas into IF signals, the plurality of filters for passing the IF signals, and a demodulating section for demodulating the IF signals. 14. The surface-acoustic-wave filter of claim 1 wherein an input IDT of one SAW filter is separated from an input IDT of another SAW filter. 15. The surface-acoustic-wave filter of claim 14 wherein each of the plurality of SAW filters includes output terminals for providing an individual output signal. 16. A surface-acoustic-wave filter comprising: a piezoelectric substrate; and a plurality of transversal surface-acoustic-wave (SAW) filters set on the piezoelectric substrate and respectively having at least two inter-digital transducer (IDT) electrodes for transceiving surface-acoustic-waves, wherein time periods for surface acoustic waves to propagate from inputs to outputs of the SAW filters differ in the SAW filters and thereby, timings of outputs from the SAW filters are different from each other; and a plurality of impedance-matching circuits connected to input sides and output sides of the filters, output timings of the impedance-matching circuits of the filters are different from each other.
