CLASSIFICATION UNCLASSIFIED PAGE 5 FULL RECORD PRINT FOR Split Aces IMSAR UWB SAR (U) The usable bandwidth of the system is 200-2000 MHz. In theory, the center frequency can be tuned to any portion of this band, although the operating bandwidth options are dependent on the selection. The equipment can be fully configured by the operator to meet local spectrum requirements, including notching out any desired portion of the transmitted band. Notches are applied via a password protected local network web interface, and the transmitter is then turned off during the bands specified. The notching parameters are stored in the radar as an electronic file. The parameters can be changed in advance of operation, or 'on the fly' to remedy a frequency conflict found in the middle of a sortie. Active notching is not currently available with this system, but could be developed if considered beneficial and/or necessary (U) Links were not created due to software limitation. Some were allowed, but in order not to confuse actual requested frequencies (200-2000MHz), none were created. The follwoing EL-CID software message appears when creating links: There are Selected Modes in this combination of equipments whose band limits no longer m"atch the Frequency Allocation Table (FAT). They have been removed from the Selected Modes grid. (Click View Link to see all existing stored modes.) This occurs when the FAT is changed after this record is built.

CLASSIFICATION UNCLASSIFIED PAGE 11 FULL RECORD PRINT FOR Split Aces IMSAR UWB SAR Remark(s) (U) (U) Output Device is Monolithic Microwave Integrated Circuit (MMIC) (U) Modulation technique is similar to Interrupted Frequency Modulated Continuous Wave. The IMSAR UWB radar varies from the typical definition of an IFMCW system in that it does not necessarily operate with a 50% duty cycle. Also, the radar is programmed so that each transmitted segment within a chirp begins where the previous segment ended. This means that the entire bandwidth is used, and the data processed as if it were an FMCW system, even though it has the same "pulsing" characteristics of an IFMCW system. (U) The out-of-band filter cutoff is designed as follows: -3 dB @ 1620 MHz, -10 dB @ 1685 MHz, -20 dB @ 1755 MHz, -40 dB @ 1860 MHz. This supports the upper limit of the current hardware, which operates up to about 1550 MHz. A near-future hardware redesign will allow for operation up to the 2000 MHz. (U) The target platform is small UAVs. For testing and development (and for convenience at other times), the system may be flown on small manned aircraft, such as a Cessna 172. (U) The IMSAR UWB radar is capable of notching out specified transmission bands to prevent interference to other systems. Notch depths of -52 dBc or better are achievable across the band. (U) A chirp is divided into some number of pulses, with each pulse covering an equal portion of the full frequency modulated operating band. The number of pulses within a chirp is computed dynamically depending on the standoff range to the target of interest. Since the PRF is a fixed value (typically 1 kHz), the pulse rate, width, and compression ratio all vary according to the number of pulses in each chirp. Also, the pulse rate and width are inversely proportional. The pulse rise and fall times are constant, and independent of bandwidth. CLASSIFICATION UNCLASSIFIED EL-CID ver. 6.0 rev 227 04/28/2016
