Zusammenfassung:	TRACKING APERTURE RADAR The transmitting antenna of a side looking radar system for high flying aircraft and space vehicles emits radar pulses which illuminate a narrow patch of terrain which is elongated in a direction orthogonal to the direction of progression of the vehicle carrying the radar system. Reflected pulses are received in a receiving antenna which illuminates an area contained within the patch and has the width of the patch but a small fraction of its range extent. The patch is scanned with the receive area. By the use of this system, for a given antenna size the previous transmitter power dependence on frequency is avoided, thus allowing much higher R.F. frequencies to be used with available transmitter power.
