Abstract:
PURPOSE: A device and a method for computing a real-time spectrum and a recording medium for recording the method are provided to reduce the amount of required computation. CONSTITUTION: A device for computing a real-time spectrum comprises an input module(510), a serial/parallel converter(520), a processor(530), and an output module(540). The input module receives a time domain signal. The serial/parallel converter converts the time domain signal into serial data and transmits the serial data to the processor. The processor computes spectrum data from the serial data. The output module outputs the computed spectrum data to the outside.
Abstract:
PURPOSE: A radar scan type recognition method using feature factors is provided to recognize radar scan types by using pulse amplitude information in accordance with pulse arrival time of detected radar signals. CONSTITUTION: Pulse amplitude information is generated according to pulse arrival time to classify received or measured radar signals into scan types, and feature factors R1, R2, and R3, representing signal concentration in time domain are calculated(S110). The R1 and a corresponding threshold value are compared(S121), the R2 and a corresponding threshold value are compared(S122), and the R3 and a corresponding threshold value are compared(S123). Detailed scan type classification for search radar signals or tracking radar signals is performed(S130,S140).
