Abstract: An adaptive nonlinear processor in which the desired radar signal together with an interfering signal is mixing with a voltage controlled oscillator and fed to a dispersive filter, the output thereof being detected and converted into gating pulses for enabling a gate circuit that is also fed by the same dispersive filter. The gated output is frequency inverted and fed to a second dispersive filter which produces an inverse Fourier transform. The signal is then mixed with the delayed output of the voltage control oscillator and band pass filtered.

Abstract: An IF side-lobe canceller having a main channel and a pair of auxiliary channels in which the signal from the main channel is mixed with a stable local oscillator and fed to a subtractor, while in each of the pair of auxiliary channels the signal from an omnidirectional antenna is fed to a mixer and then to the subtractor. The subtractor's output is fed to mixers together with the signals from the omnidirectional antennas. The outputs of these mixers are fed to additional mixers together with the mixed outputs of the stable local oscillator and a second oscillator.

Abstract: An intermediate frequency sidelobe canceller having two cancellation points, one delayed with respect to the other. By utilizing the control signal generated by the loop associated with the undelayed cancellation point to control the cancelling signal at the delayed cancellation point, the "lock-on" time of the delayed cancellation point can be reduced to zero.

Abstract: A decoy missile having a high moment of inertia with a corresponding reduction of the natural oscillation frequency for simulating reentry of a ballistic nose cone into the earth's atmosphere. High density ballast material disposed in the forward section is in proportional relationship to similar ballast material in the base section such that the distance between the center of pressure and the center of gravity is equal to one-half the base diameter.
