4. Consider two-stage systems having both doppler and range resolution. 



5. Investigate the effect of clutter and interference on the performance of 

 the two-stage system. 



6. Implement a two-stage system as soon as a suitable antenna is available; 

 perform two-stage and conventional tests with live targets to verify performance 



predictions
