This paper describes the design and intricacies of a wideband digital chirp receiver utilizing a one-bit ADC (Analog to Digital Converter) to measure the carrier frequency and chirp rate of unknown received signals which have very high chip rates. The core of the chirp receiver is composed of monobit IFM receivers which are low cost and very accurate.

The complex signals instantaneous frequency measurement using multichannel IFM systems
15th International Conference on Microwaves, Radar and Wireless Communications (IEEE Cat. No.04EX824), 2004The capabilities of a multichannel IFM system for instantaneous frequency measurement of complex pulse signals are presented. The frequency characteristics of the IFM systems are correct for CW and long pulse signals. For complex short pulse signals with a wide spectrum, the IFM's frequency characteristics can be changed depending on the signal ...

Instantaneous Frequency Measurement (IFM) Receivers
2005In this chapter, the operating principles of IFM receivers, some trade-offs in the designs, and several schemes for digitizing the outputs of the video amplitude will be discussed. Since an IFM receiver can measure only one input signal at a time, one continuous-wave (CW) signal will block the receiver from measuring other input signals.
