A communication waveform for radar
2010 8th International Conference on Communications, 2010This paper discusses some opportunities created by using Orthogonal Frequency Division Multiplexing signals for radar and communication at the same time. Two examples of opportunities in radar are proposed, i.e. solving the unambiguous radial speed in a single transmission and improving the signal-to-background contrast.

In this chapter, BPSK radar waveforms for spectrum sharing are designed, i.e., the problem of designing MIMO radar BPSK waveform to match a given beampattern in the presence of a cellular system is considered.

On the role of waveform diversity in MIMO radar
Digital Signal Processing, 2011MIMO radar employs multiple antennas to simultaneously transmit diverse waveforms, as well as multiple antennas to receive the radar returns. This paper studies the role of waveform diversity in MIMO radar as separate and distinct from the role of the multiple transmit antennas.

Detection performance is optimized and range and doppler both improved by maximizing the SNR. Since this needs the pulse to have high energy, long pulses are required unless a very high power transmitter is available. Long pulses also permit good doppler accuracy, but, for simple pulses, give poor range accuracy.

Most modern radars use a phase-modulated carrier for range and range-rate measurements. High carrier frequencies are generally selected when the application requires narrow beamwidths with a constrained aperture area. However, for applications which require the unambiguous determination of both range and range-rate, the high carrier frequency seriously
