Phased array radar seeker, which has complex composition, various measurement indexes and huge amount of test data, generally requires to be tested in microwave anechoic chamber which satisfies far field conditions. This paper introduces one portable testing method for phased array radar seeker and composition of test system, analyses portable testing method and portable seeker shield design principle, and explains displacement angle fluctuation which occasionally occurs in phased array radar seeker angle tracking parameter test using this test system. This method is practical, easy to operate and low in cost, and it can well satisfy the requirement of field test or environment test. This phased array radar seeker portable testing method and its analysis result are of high value in practice.
