Herein, we propose a model for seeding the radar data cube with target signals and calculate both asymptotic and finite training data detection losses. In general, both the location and strength of the corruptive target signals influence performance: under practical conditions, SINR loss can exceed 10 dB. Measured MCARM data confirms the presence of ample ground moving target signals in the radar field of regard under typical operating conditions. We conclude by briefly considering several mitigating strategies as well.","PeriodicalId":214828,"journal":{"name":"Proceedings of the 2001 IEEE Radar Conference (Cat.

A harmful influence of the ambiguity function (AF) sidelobes on target detection and parameter measurement is a significant obstacle to using the long pulse duration complex modulated waveform in marine radars. We discuss waveforms and linked processing for clutter suppression by means of AF sidelobe reduction. Some relationships for the quasi-continuous complex signal synthesis of amplitude-phase modulated waveform (APW) are given. The received signals are processed by a mismatch filter. The synthesis criterion of the mismatch filter structure was a root mean square minimization of the output signal sidelobe level. The computer synthesis software of the quasi-optimum mismatch processing structure has been developed. We give some examples of the waveform and mismatch algorithms of their professing which could be used in marine and coastal radars for surveillance of surface targets and navigation.","PeriodicalId":214828,"journal":{"name":"Proceedings of the 2001 IEEE Radar Conference (Cat.

Remarkably, the second stage possesses the constant false alarm rate property with respect to all of the unknown statistics of slick-free returns.","PeriodicalId":214828,"journal":{"name":"Proceedings of the 2001 IEEE Radar Conference (Cat.
