Abstract: A system includes a radio frequency transceiver. A baseband processor includes an automatic gain control module. The automatic gain control module has a gain that changes from and subsequently returns to a predetermined value each time the radio frequency transceiver receives a radio frequency signal. The baseband processor is configured to selectively generate an interrupt signal each time a radio frequency signal is received based on a magnitude of the change in the gain of the automatic gain control module and a length of time in which the gain returns to the predetermined value. A control module is configured to identify a radio frequency signal received by the radio frequency transceiver as a radar signal in response to the baseband processor having generated a plurality of interrupt signals at substantially equal time intervals.

Abstract: The present invention relates to a catalyst for catalytic cracking fluidized-bed, and the technical problems to be primarily solved by the present invention are high reaction temperature, low cryogenic activity of catalysts and worse selectivity during the preparation of ethylene-propylene by catalytically cracking naphtha. The present invention uses the composition having the chemical formula (on the basis of the atom ratio): AaBbPcOx, so as to magnificently solve said problems. The present invention therefore can be industrially used to produce ethylene and propylene by catalytically cracking naphtha.

The network device includes a control module that selectively measures N time intervals between one of adjacent and non-adjacent control signals, wherein N is an integer greater than 1, and that selectively determines that the RF signal is a radar signal when the N time intervals are substantially equal.

Abstract: A method for preparation of ethylene and propylene by catalytic cracking using a fluid-bed catalyst. The main technical problems to be solved are a relatively high reaction temperature, and low activities and poor selectivities of the catalyst at a low temperature, during the reaction for preparing ethylene and propylene by catalytically cracking naphtha.
