Radar Range Equation Problem. Please fill in the following sentences with increase/decrease/not change. Justify your answer using the radar range equation, geometry or other basic equations whenever possible. when the radar's range Example: The power of a reflecting radar signal should separation from the reflecting target increases. Answer: decrease. Pt is inversely proportional to R¹. When R increases, Pe decreases. for a target that is moving A. The frequency of a reflecting signal should radially away from the radar. B. The transmit pulse duration should with increasing PRI. C. The time-delay of a target return within a PRI should_ antenna scan rate. D. For an unmodulated waveform (e.g., a simple sinusoidal), noise power in a radar receiver should with decreasing pulse length. with increasing E. If mean ground or ocean surface reflectivity does not change with range, the signal to clutter ratio should, with increasing range. F. The mean RCS of a target should with decreasing range. G. The wavelength of a signal transmitted from a stationary radar at a single carrier frequency should when its propagates from one layer in the atmosphere with a lower index of refraction to a layer with a higher index of refraction. H. When multipath is present, the ratio of the direct line-of-sight distance to the target and the indirect (virtual target) distance should with decreasing range. I. The probability of detecting a target should detection threshold. as you increase the signal J. The probability of false alarms (noise detections) should the signal detection threshold. as you decrease
