A miniature hand held smart I-band and K-band beacon transponder is proposed to provide location, data transmission, and IFF applications. Based on the SMI I-band Microponder which has single, double, triple, and active pulse operations, the proposed beacon adds a k-band capability with smart band selection according to interrogation pulse frequency. For data transmission, its pulse positon modulation (PPM) architecture will allow data input through an RS-232 data interface, transmission of SELCAL codes for IFF operation, and GPS location data. Its agile AGC receiver responds to weak as well as strong iterrogation pulses in quick succession. The target life for its 9-V battery power supply is 24 hours of continuous operation.
