<P>PROBLEM TO BE SOLVED: To provide a system and a method for correctly determining nonlinearity of a TWTA when it varies in accordance with time/temperature. <P>SOLUTION: The method includes a step 1302 of receiving and demodulating a signal, and a step 1304 of generating an ideal signal 1320 from the demodulated signal. It further includes steps 1324/1326 of coherently averaging the received signal to reduce noise, and estimating performance characteristics from a difference between the coherently averaged ideal signal 1320 and the received signal. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
