摘要： A method is disclosed for target ray resolution in coherent, conically scanned radar when a target image is present. An envelope detector and frequency discriminator operate on the IF signal. The fundamental and second harmonic components of the conical scan out of the discriminator are used in a computer along with the DC, fundamental, and second harmonic of the envelope out of the detector to solve five equations in five unknowns. That yields the elevation angles to the target and its image. The larger of the two angles is selected as the elevation angle to the target. The first harmonic and the DC component of the envelope are employed to produce an estimate of the target azimuth angle.
