Comments on "Synthesis of adaptive monopulse patterns" [with reply]

In the recent paper (see ibid., vol.47, no.5, p.773-4, May 1999) Fante determines the weight vector w/sub /spl Delta// for the difference beam subject to the constant slope of the ratio /spl Delta///spl Sigma/. Junhao Xie states that the method is quite general and that the sum/difference beam weight vector should be simplified further.
