Reciprocal radar waveforms

IEEE Transactions on Aerospace and Electronic Systems, 1991
Digitally coded radar waveforms can be used to obtain large time-bandwidth products (pulse compression ratios). It is demonstrated that periodic radar waveforms with zero sidelobes or almost zero sidelobes can be defined. A perfect periodic code is a periodic code whose autocorrelation function has zero sidelobes and whose amplitude is uniform (maximum

Radar watermark waveform

IET Conference Publications, 2009
A novel method of anti deceiving jamming is proposed. Normal radar waveform is vulnerable to jammer's interception and analysis. If modify the phase of normal waveform according to minimum correlation between the primitive and modified one, and if the phase varying is minor, the jammer may not perceive it and still transmit the intercepted normal ...

Robust Waveform Design for MIMO Radars

IEEE Transactions on Signal Processing, 2011
The problem of robust waveform design for multiple-input, multiple-output radars equipped with widely spaced antennas is addressed here. Robust design is needed as a number of parameters may be unknown, e.g., the target scattering covariance matrix and the disturbance covariance matrix.
