These systems typically achieve the bandwidth necessary for range resolution through transmission of either a stepped-frequency or chirped waveform. Moreover Radar ambiguity function (RAF) is also analysed and used for studying various performance parameters of both NLFM and LFM waveforms. Key Words: Linear frequency modulated waveform, non-linear frequency modulated waveform, radar ambiguity function. 1.

Cognitive radar experiments are exceptionally difficult to perform due to the adaptive nature of the sensing involved. In contrast to development of algorithms to be applied to already-captured data, it can be difficult to obtain appropriate data sets to prove cognitive radar concepts.A radar assembly for receiving signals at spaced frequencies from an unknown transmitting source comprising a receiver operative to receive signals; the receiver comprising a series of channels, each channel comprising a low pass filter configured to allow passage of a signal from an unknown transmitting source, an analog to digital converter configured to …Nonlinear radars are generally used for clutter suppression purposes.
