Abstract
This report presents the final test results for the Portable Interference Frequency Sources (PIFS) following the modifications to enable remote control of their functions. The PIFS are two identical units which serve as radar beacons for the Experimental Array Radar System (EARS). They operate over the same 8.900 to 9.400 GHz bandwidth that the EARS transmits on. They can transmit a continuous wave (CW) signal. They can also modulate the CW signal with a low frequency doppler or a 10 MHz bandwidth noise source. The system controller (syscon) can control the transmit frequency, the attenuation, the output on/off enable, the modulation type and the doppler frequency of the PIFS. Each PIFS can be controlled independently, with two in operation simultaneously. In addition, the syscon can request the PIFS status and put the PIFS into a standby mode, to conserve battery power. A small hand-held VT-100 compatible ;terminal is used at each PIFS for local control and display of the status. Power is derived from two gell-cell batteries, contained in a separate enclosure. The PIFS can operate at up to 15 kilometers away from the EARS, depending on the antennas used for the radio link and their orientation to each other.
