Match filtering to resolve multiple targets through pulse compression has been analyzed as well for LFM coded signal, simulation of two closely spaced targets with overlapping received echo, simulation for received uncompressed noisy echo for LFM codded signal and performed autocorrelation for signal with two target echos and simulation of pulse compression of three LFM coded targets have been done.

Binary codes with low autocorrelation sidelobe levels and high Discriminating factors are useful for radar pulse compression [4], channel estimation, and spread spectrum communication applications.
The aircraft is configured to carry torpedoes and is fitted with state of the art pulse compression radar, low frequency dipping sonar, red-warning receiver and Doppler navigation system.
Pulse compression was also marketed as a kind of access control for signals, and many customers, therefore, saved the cost of an extra channel for sidelobe blanking, which could be justified as long as matched jamming pulses were not technically feasible.
Complex pulse compression can be applied to a pulse without the need to manually perform complex calculations.
