Sidelobe suppression in minimum redundancy linear arrays

[1992] IEEE Sixth SP Workshop on Statistical Signal and Array Processing, 2003
This paper investigates the issue of finding appropriate weighting coefficients which suppress a maximum number of sidelobes to an arbitrarily specified level. The performance of the resulting system is compared with an equi-spaced array having the same aperture. >

A novel polyphase code for sidelobe suppression

2007 International Waveform Diversity and Design Conference, 2007
A binary code sequence attained by modification of a Golay code is proposed. This code has sidelobes which are out of phase with the main lobe, a property which facilitates their removal. Unknown delay-dependent phase terms proclude the multiplexing of a Golay pair in frequency.

Suppression of sidelobe scatterers in an AESA FMCW radar

2008 IEEE Radar Conference, 2008
This paper describes an active electronically scanned array (AESA) FMCW radar with eight transceivers. Each transceiver has its own direct digital synthesizer (DDS) for signal generation which enables digital beam forming on transmit as well as on receive.

Suppression of Range Sidelobes of Random Modulations

2018 International Conference on Radar (RADAR), 2018
A technique is described to cancel the range sidelobes due to the use of a random waveform for radars. The technique is based on the deterministic relationship (a complex conjugation) between the range sidelobes either side of a target. The technique is demonstrated by simulation and is also shown to work with recorded data from a practical noise radar

Suppression of range sidelobes in bistatic radars

Proceedings of the IEEE, 1980
Conventional weighting schemes give little or no suppression of some of the range sidelobes of a linear-FM rectangular pulse passed through a matched filter.
