Summary:Noise power and noise figure are detailedly analysed and deduced in theory for mult-port network in active electrically scanned array(AESA) radar, especially in AESA radar. Mathematical expressions of output noise power and total noise figure of network are given out under various conditions. Accordingly, this provides a basis of theories for multi-port network and radar receiver system design, the test method of array noise figure. Finally two application examples are gived to verify accuracy of the formula.
