TELEDYNE DEFENCE LIMITED 2-18 GHz Radar Warning Receiver Technical Datasheet RR017 A Teledyne Technologies Company Features 2 to 18 GHz Frequency range 25MHz Frequency resolution 0.2dB Amplitude resolution Pulse Descriptor Word Output USB2 interface Sensitivity –57dBm (or better) Small form factor Applications Affordable Radar Warning Receiver for AFV UAV Remote sensing Air, sea and land platforms Product Description The RR017 is designed for Radar Warning Receiver (RWR) applications where low cost and small size and are of prime importance, with filtering, amplification, detection and pulse parameter measurement being combined into one multifunction unit. Two amplitude measurement channels allow direction finding by amplitude comparison between adjacent antennas. A 20dB switched attenuator can be selected to allow amplitude measurement above –15dBm. An IFM, fed from one of the amplitude channels via an SPDT switch, performs 10 bits of frequency measurement on the selected input. Frequency resolution is nominally 25 MHz over a 2 to 18 GHz band. The RR017 is internally triggered and generates a full PDW giving the following data: Time of arrival, Pulse amplitude (from the two selected antennas), Pulse frequency and Pulse width. The standard data interface is USB2 with optional 50MHz clocked 16-bit parallel interface via a separate 37 way MDM connector. The small size eases the burden on UAV and AFV payloads in particular and the reduced power consumption renders a double benefit, as a smaller, lighter power supply is required.RF connections are made by SMA, DC power & USB2 uses a 25 way MDM, parallel data uses a separate 37 way MDM connector. External 50 MHz clock input can be selected to operate the time of arrival (TOA) counter (shared clock source for the parallel data output PDWs), hence the PDWs generated have fully correlated TOA digits.

RR017 rev 3.0 March 2011 Page 2 of 8 TELEDYNE DEFENCE LIMITED 2-18 GHz Radar Warning Receiver Technical Datasheet RR017 A Teledyne Technologies Company Block Diagram Operating Modes LVTTL Control inputs are provided for direct control over the Input selection, the IFM measurement channel and the switched attenuator but in addition these functions may be controlled from the USB2 interface although this introduces a delay depending on the USB2 transfer time. An auto mode is available for the attenuator and the IFM channel to simplify the operation. The IFM can be directed to either of the measurement channels by the use of a TTL or USB command or alternatively using Auto Freq mode the internal thresholding determines the amplitude channel with the highest signal and route the IFM accordingly. This process functions on a pulse-by-pulse basis but reduces the minimum pulse width to 120ns due to the switching delay. The mode of operation can be specified from the USB2 interface and can be changed as required. The switched attenuator can be introduced, to both channels simultaneously, to enable the amplitude of high-level signals to be measured. This can be manually controlled or using Auto Atten mode the system detects on overrange measurement and switch the attenuation automatically. This process functions on a pulse-by-pulse basis but reduces the minimum pulse width to 200ns due to the switching delay. RR017 generates a PDW following the end of a received pulse, the maximum reported pulse width is 650us. Under CW conditions a PDW is generated after a pre-settable time, up to the maximum 650us with the CW Present flag set, PDWs continue to be generated with the same interval for the duration of the CW signal. Parallel Data Transfer Each PDW is transferred in 8 clock cycles. The diagram illustrates a full transfer plus the start of the next transfer. Each Word block represents a portion of PDW data.
