Abstract
A radar of particular use at close range has a CRT that is scanned in a spiral fashion by applying phase quadrature sinusoidal signals to resonant deflection coils. A digitizer converts the radar return signals to multi-bit signals which are supplied to a memory with signals for alternate pixels stored in different halves of the memory. The apparatus reads out signals from one half of the memory during one scan and reads out signals from the other half of the memory during the next scan so that they are interleaved with the pixels on the display brightened by the first scan.
