Abstract

Phased array radar or radar with array feed reflector antenna is made up of multiple channels, and the radar detection range is closely related to the noise figure (NF). Before the radar being put into operation, it's necessary to measure its NF to evaluate the system performance. Here, an NF measurement method of multi-channel radar receiving system is analyzed in detail with the theory of equivalent conversion of a multi-port network model into a two-port network model, combining with channel characteristics of array antenna with various amplitude weighting. To prove the correctness of the measurement method, a four-channel example is presented to show that the equivalent conversion method is feasible, and it also demonstrates that it is possible to precisely estimate NF of a multi-channel system through computation.
